Installation Path B - Manual Installation Using Cloudera Manager Packages

Before You Begin

Install and Configure Databases

Cloudera Manager Server, Cloudera Management Service, and the Hive Metastore data is stored in a database. Install and configure required databases following the instructions in Cloudera Manager and Managed Service Databases.

(CDH 5 only) On RHEL and CentOS 5, Install Python 2.6 or 2.7

Python 2.6 or 2.7 is required to run Hue. RHEL 5 and CentOS 5, in particular, require the EPEL repository package.

In order to install packages from the EPEL repository, first download the appropriate repository rpm packages to your machine and then install Python using yum. For example, use the following commands for RHEL 5 or CentOS 5:
$ su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm'
...
$ yum install python26

Establish Your Cloudera Manager Repository Strategy

Cloudera recommends installing products using package management tools such as yum for Red Hat compatible systems, zypper for SLES, and apt-get for Debian/Ubuntu. These tools depend on access to repositories to install software. For example, Cloudera maintains Internet-accessible repositories for CDH and Cloudera Manager installation files. Strategies for installing Cloudera Manager include:

  • Standard Cloudera repositories. For this method, ensure you have added the required repository information to your systems. For Cloudera Manager repository locations and client repository files, see Cloudera Manager Version and Download Information.
  • Internally hosted repositories. You might use internal repositories for environments where hosts do not have access to the Internet. In such a case, ensure your environment is properly prepared. For more information, see Understanding Custom Installation Solutions.

Red Hat-compatible

  1. Save the appropriate Cloudera Manager repo file (cloudera-manager.repo) for your system:
  2. Copy the repo file to the /etc/yum.repos.d/ directory.

SLES

  1. Run the following command:
    $ sudo zypper addrepo -f http://archive.cloudera.com/cm5/sles/11/x86_64/cm/cloudera-manager.repo
  2. Update your system package index by running:
    $ sudo zypper refresh

Ubuntu or Debian

  1. Save the appropriate Cloudera Manager list file (cloudera.list) for your system:
  2. Copy the content of that file and append it to the content of the cloudera.list in the /etc/apt/sources.list.d/ directory.
  3. Update your system package index by running:
    $ sudo apt-get update

Install the Oracle JDK

Install the Oracle Java Development Kit (JDK) on the Cloudera Manager Server host.

The JDK is included in the Cloudera Manager 5 repositories. Once you have the repo or list file in the correct place, you can install the JDK as follows:
OS Command
RHEL
$ sudo yum install oracle-j2sdk1.7
SLES
$ sudo zypper install oracle-j2sdk1.7
Ubuntu or Debian
$ sudo apt-get install oracle-j2sdk1.7

Install the Cloudera Manager Server Packages

Install the Cloudera Manager Server packages either on the host where the database is installed, or on a host that has access to the database. This host need not be a host in the cluster that you want to manage with Cloudera Manager. On the Cloudera Manager Server host, type the following commands to install the Cloudera Manager packages.
OS Command
RHEL, if you have a yum repo configured
$ sudo yum install cloudera-manager-daemons cloudera-manager-server
RHEL,if you're manually transferring RPMs
$ sudo yum --nogpgcheck localinstall cloudera-manager-daemons-*.rpm
$ sudo yum --nogpgcheck localinstall cloudera-manager-server-*.rpm
SLES
$ sudo zypper install cloudera-manager-daemons cloudera-manager-server 
Ubuntu or Debian
$ sudo apt-get install cloudera-manager-daemons cloudera-manager-server 

Set up a Database for the Cloudera Manager Server

Set up the Cloudera Manager Server database as described in Setting up the Cloudera Manager Server Database.

(Optional) Install Cloudera Manager Agent, CDH, and Managed Service Software

You can have Cloudera Manager install Cloudera Manager Agent packages or manually install the packages yourself. Similarly, you can allow Cloudera Manager to install CDH and managed service software or manually install the software yourself.

If you choose to have Cloudera Manager install the software (in Choose Software Installation Method and Install Software), you must satisfy the requirements described in Choosing an Installation Path. If you satisfy the requirements and choose to have Cloudera Manager install software, you can go to Start the Cloudera Manager Server. Otherwise, proceed with the following sections.

Install the Oracle JDK

Install the Oracle JDK on the cluster hosts. Cloudera Manager 5 can manage both CDH 5 and CDH 4, and the required JDK version varies accordingly:

Install Cloudera Manager Agent Packages

If you to manually install the packages yourself, on every Cloudera Manager Agent host (including those that will run one or more of the Cloudera Management Service roles: Service Monitor, Activity Monitor, Event Server, Alert Publisher, Reports Manager) do the following:
  1. Use one of the following commands to install the Cloudera Manager Agent packages:
    OS Command
    RHEL, if you have a yum repo configured:
    $ sudo yum install cloudera-manager-agent cloudera-manager-daemons
    RHEL, if you're manually transferring RPMs:
    $ sudo yum --nogpgcheck localinstall cloudera-manager-agent-package.*.x86_64.rpm cloudera-manager-daemons
    SLES
    $ sudo zypper install cloudera-manager-agent cloudera-manager-daemons
    Ubuntu or Debian
    $ sudo apt-get install cloudera-manager-agent cloudera-manager-daemons
  2. On every Cloudera Manager Agent host, configure the Cloudera Manager Agent to point to the Cloudera Manager Server by setting the following properties in the /etc/cloudera-scm-agent/config.ini configuration file:
    Property Description
    server_host Name of host where the Cloudera Manager Server is running.
    server_port Port on host where the Cloudera Manager Server is running.
    For more information on Agent configuration options, see Agent Configuration File.

Install CDH and Managed Service Packages

For more information about manually installing CDH packages, see CDH 4 Installation Guide or CDH 5 Installation Guide.

  1. Choose a repository strategy:
    • Standard Cloudera repositories. For this method, ensure you have added the required repository information to your systems.
    • Internally hosted repositories. You might use internal repositories for environments where hosts do not have access to the Internet. In such a case, ensure your environment is properly prepared. For more information, see Understanding Custom Installation Solutions.

Start the Cloudera Manager Server

  Important: When you start the Cloudera Manager Server and Agents, Cloudera Manager assumes you are not already running HDFS and MapReduce. If these services are running:
  1. Shut down HDFS and MapReduce. See Stopping Services (for CDH 4) or Stopping Services (for CDH 5) for the commands to stop these services.
  2. Configure the init scripts to not start on boot, use commands similar to those shown in Configuring init to Start Core Hadoop System Services or Configuring init to Start Core Hadoop System Services but disable the start on boot (for example, $ sudo chkconfig hadoop-hdfs-namenode off).
Contact Cloudera Support for help converting your existing Hadoop configurations for use with Cloudera Manager.
  1. Run this command on the Cloudera Manager Server host:
    $ sudo service cloudera-scm-server start
    If the Cloudera Manager Server does not start, see Troubleshooting Installation and Upgrade Problems.

(Optional) Start the Cloudera Manager Agents

If you installed the Cloudera Manager Agent packages in Install Cloudera Manager Agent Packages, run this command on each Agent host:
$ sudo service cloudera-scm-agent start
When the Agent starts up, it contacts the Cloudera Manager Server. If there is a communication failure between a Cloudera Manager Agent and Cloudera Manager Server, see Troubleshooting Installation and Upgrade Problems.

When the Agent hosts reboot, cloudera-scm-agent starts automatically.

Start the Cloudera Manager Admin Console

The Cloudera Manager Server URL takes the following form http://Server host:port, where Server host is the fully-qualified domain name or IP address of the host where the Cloudera Manager Server is installed and port is the port configured for the Cloudera Manager Server. The default port is 7180.
  1. Wait several minutes for the Cloudera Manager Server to complete its startup. To observe the startup process you can perform tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log on the Cloudera Manager Server host. If the Cloudera Manager Server does not start, see Troubleshooting Installation and Upgrade Problems.
  2. In a web browser, enter http://Server host:7180, where Server host is the fully-qualified domain name or IP address of the host where you installed the Cloudera Manager Server. The login screen for Cloudera Manager Admin Console displays.
  3. Log into Cloudera Manager Admin Console. The default credentials are: Username: admin Password: admin. Cloudera Manager does not support changing the admin username for the installed account. You can change the password using Cloudera Manager after you run the installation wizard. While you cannot change the admin username, you can add a new user, assign administrative privileges to the new user, and then delete the default admin account.

Choose Cloudera Manager Edition and Hosts

The following instructions describe how to use the Cloudera Manager wizard to choose which edition of Cloudera Manager you are using and which hosts will run CDH and managed services.

  1. When you start the Cloudera Manager Admin Console, the install wizard starts up. Click Continue to get started.
  2. Choose which edition to install:
    • Cloudera Express, which does not require a license, but provides a somewhat limited set of features.
    • Cloudera Enterprise Data Hub Edition Trial, which does not require a license, but expires after 60 days and cannot be renewed
    • Cloudera Enterprise with one of the following license types:
      • Basic Edition
      • Flex Edition
      • Data Hub Edition
    If you choose Cloudera Express or Cloudera Enterprise Data Hub Edition Trial, you can elect to upgrade the license at a later time. See Managing Licenses.
  3. If you have elected Cloudera Enterprise, install a license:
    1. Click Upload License.
    2. Click the document icon to the left of the Select a License File text field.
    3. Navigate to the location of your license file, click the file, and click Open.
    4. Click Upload.
    Click Continue to proceed with the installation.
  4. Click Continue in the next screen. The Specify Hosts page displays.
  5. Do one of the following:
    • If you installed Cloudera Agent packages in Install Cloudera Manager Agent Packages, choose from among hosts with the packages installed:
      1. Click the Currently Managed Hosts tab.
      2. Choose the hosts to add to the cluster.
    • Search for and choose hosts:
      1. To enable Cloudera Manager to automatically discover hosts on which to install CDH and managed services, enter the cluster hostnames or IP addresses. You can also specify hostname and IP address ranges. For example:
        Range Definition Matching Hosts
        10.1.1.[1-4] 10.1.1.1, 10.1.1.2, 10.1.1.3, 10.1.1.4
        host[1-3].company.com host1.company.com, host2.company.com, host3.company.com
        host[07-10].company.com host07.company.com, host08.company.com, host09.company.com, host10.company.com

        You can specify multiple addresses and address ranges by separating them by commas, semicolons, tabs, or blank spaces, or by placing them on separate lines. Use this technique to make more specific searches instead of searching overly wide ranges. The scan results will include all addresses scanned, but only scans that reach hosts running SSH will be selected for inclusion in your cluster by default. If you don't know the IP addresses of all of the hosts, you can enter an address range that spans over unused addresses and then deselect the hosts that do not exist (and are not discovered) later in this procedure. However, keep in mind that wider ranges will require more time to scan.

      2. Click Search. Cloudera Manager identifies the hosts on your cluster to allow you to configure them for services. If there are a large number of hosts on your cluster, wait a few moments to allow them to be discovered and shown in the wizard. If the search is taking too long, you can stop the scan by clicking Abort Scan. To find additional hosts, click New Search, add the host names or IP addresses and click Search again. Cloudera Manager scans hosts by checking for network connectivity. If there are some hosts where you want to install services that are not shown in the list, make sure you have network connectivity between the Cloudera Manager Server host and those hosts. Common causes of loss of connectivity are firewalls and interference from SELinux.
      3. Verify that the number of hosts shown matches the number of hosts where you want to install services. Deselect host entries that do not exist and deselect the hosts where you do not want to install services. Click Continue. The Select Repository page displays.
  6. Click Continue. The Select Repository page displays.

Choose Software Installation Method and Install Software

The following instructions describe how to use the Cloudera Manager wizard to install Cloudera Manager Agent, CDH, and managed service software.

  1. Select how CDH and managed service software is installed: packages or parcels:
    • Use Packages - If you did not install packages in Install CDH and Managed Service Packages, click the package versions to install. Otherwise, select the CDH version (CDH 4 or CDH 5) that matches the packages that you installed manually.
    • Use Parcels
      1. Choose the parcels to install. The choices you see depend on the repositories you have chosen – a repository may contain multiple parcels. Only the parcels for the latest supported service versions are configured by default.
        You can add additional parcels for previous versions by specifying custom repositories. For example, you can find the locations of the previous CDH 4 parcels at http://archive.cloudera.com/cdh4/parcels/. Or, if you are installing CDH 4.3 and want to use Sentry for Policy File-Based Hive Authorization, you can add the Sentry parcel using this mechanism.
        1. To specify the parcel directory, local parcel repository, add a parcel repository, or specify the properties of a proxy server through which parcels are downloaded, click the More Options button and do one or more of the following:
          • Parcel Directory and Local Parcel Repository Path - Specify the location of parcels on cluster hosts and the Cloudera Manager Server host.
          • Parcel Repository - In the Remote Parcel Repository URLs field, click the button and enter the URL of the repository. The URL you specify is added to the list of repositories listed in the Configuring Server Parcel Settings page and a parcel is added to the list of parcels on the Select Repository page. If you have multiple repositories configured, you will see all the unique parcels contained in all your repositories.
          • Proxy Server - Specify the properties of a proxy server.
        2. Click OK.
  2. If you did not install Cloudera Manager Agent packages in Install Cloudera Manager Agent Packages, do the following:
    1. Select the release of Cloudera Manager Agent to install. You can choose either the version that matches the Cloudera Manager Server you are currently using or specify a version in a custom repository.
    2. If you opted to use custom repositories for installation files, you can provide a GPG key URL that applies for all repositories.
  3. Click Continue. The Configure Java Encryption page displays.
  4. If your local laws permit you to deploy unlimited strength encryption and you are running a secure cluster, check the Install Java Unlimited Strength Encryption Policy Files checkbox. Click Continue.
  5. If you chose to have Cloudera Manager install packages, specify host installation properties:
    1. Select root or enter the user name for an account that has password-less sudo permission.
    2. Select an authentication method:
      • If you choose to use password authentication, enter and confirm the password.
      • If you choose to use public-key authentication provide a passphrase and path to the required key files.
    3. You can choose to specify an alternate SSH port. The default value is 22.
    4. You can specify the maximum number of host installations to run at once. The default value is 10.
  6. Click Continue. If you did not install packages in (Optional) Install Cloudera Manager Agent, CDH, and Managed Service Software, Cloudera Manager installs the Oracle JDK, Cloudera Manager Agent,packages and CDH and managed service packages or parcels. During the parcel installation, progress is indicated for the two phases of the parcel installation process (Download and Distribution) in a separate progress bars. If you are installing multiple parcels you will see progress bars for each parcel. When the Continue button appears at the bottom of the screen, the installation process is completed. Click Continue.
  7. Click Continue. The Host Inspector runs to validate the installation, and provides a summary of what it finds, including all the versions of the installed components. If the validation is successful, click Finish. The Cluster Setup page displays.

Add Services

The following instructions describe how to use the Cloudera Manager wizard to configure and start CDH and managed services.

  1. In the first page of the Add Services wizard you choose the combination of services to install and whether to install Cloudera Navigator:
    • Click the radio button next to the combination of services to install:
      CDH 4 CDH 5
      • Core Hadoop - HDFS, MapReduce, ZooKeeper, Oozie, Hive, and Hue
      • Core with HBase
      • Core with Impala
      • All Services - HDFS, MapReduce, ZooKeeper, HBase, Impala, Oozie, Hive, Hue, and Sqoop
      • Custom Services - Any combination of services.
      • Core Hadoop - HDFS, YARN (includes MapReduce 2), ZooKeeper, Oozie, Hive, Hue, and Sqoop
      • Core with HBase
      • Core with Impala
      • Core with Search
      • Core with Spark
      • All Services - HDFS, YARN (includes MapReduce 2), ZooKeeper, Oozie, Hive, Hue, Sqoop, HBase, Impala, Solr, Spark, and Key-Value Store Indexer
      • Custom Services - Any combination of services.
      As you select the services, keep the following in mind:
      • Some services depend on other services; for example, HBase requires HDFS and ZooKeeper. Cloudera Manager tracks dependencies and installs the correct combination of services.
      • In a CDH 4 cluster, the MapReduce service is the default MapReduce computation framework. Choose Custom Services to install YARN or use the Add Service functionality to add YARN after installation completes.
          Important: You can create a YARN service in a CDH 4 cluster, but it is not considered production ready.
      • In a CDH 5 cluster, the YARN service is the default MapReduce computation framework. Choose Custom Services to install MapReduce or use the Add Service functionality to add MapReduce after installation completes.
          Important: In CDH 5 the MapReduce service has been deprecated. However, the MapReduce service is fully supported for backward compatibility through the CDH 5 life cycle.
      • The Flume service can be added only after your cluster has been set up.
    • If you have chosen Data Hub Edition Trial or Cloudera Enterprise, optionally check the Include Cloudera Navigator checkbox to enable Cloudera Navigator. See the Cloudera Navigator Documentation.
    Click Continue. The Customize Role Assignments page displays.
  2. Customize the assignment of role instances to hosts. The wizard evaluates the hardware configurations of the hosts to determine the best hosts for each role. The wizard assigns all worker roles to the same set of hosts to which the HDFS DataNode role is assigned. These assignments are typically acceptable, but you can reassign role instances to hosts of your choosing, if desired.

    Click a field below a role to display a dialog containing a pageable list of hosts. If you click a field containing multiple hosts, you can also select All Hosts to assign the role to all hosts or Custom to display the pageable hosts dialog.

    The following shortcuts for specifying hostname patterns are supported:
    • Range of hostnames (without the domain portion)
      Range Definition Matching Hosts
      10.1.1.[1-4] 10.1.1.1, 10.1.1.2, 10.1.1.3, 10.1.1.4
      host[1-3].company.com host1.company.com, host2.company.com, host3.company.com
      host[07-10].company.com host07.company.com, host08.company.com, host09.company.com, host10.company.com
    • IP addresses
    • Rack name

    Click the View By Host button for an overview of the role assignment by hostname ranges.

  3. When you are satisfied with the assignments, click Continue. The Database Setup page displays.
  4. On the Database Setup page, configure settings for required databases:
    1. Enter the database host, database type, database name, username, and password for the database that you created when you set up the database.
    2. Click Test Connection to confirm that Cloudera Manager can communicate with the database using the information you have supplied. If the test succeeds in all cases, click Continue; otherwise check and correct the information you have provided for the database and then try the test again. (For some servers, if you are using the embedded database, you will see a message saying the database will be created at a later step in the installation process.) The Review Changes page displays.
  5. Review the configuration changes to be applied. Confirm the settings entered for file system paths. The file paths required vary based on the services to be installed.
      Warning: DataNode data directories should not be placed on NAS devices.
    Click Continue. The wizard starts the services.
  6. When all of the services are started, click Continue. You will see a success message indicating that your cluster has been successfully started.
  7. Click Finish to proceed to the Home Page.

Configure Cluster CDH Version for Package Installs

If you have installed CDH as a package, after an install or upgrade make sure that the cluster CDH version matches the package CDH version, using the procedure in Configuring the CDH Version for a Cluster in Managing Clusters with Cloudera Manager. If the cluster CDH version does not match the package CDH version, Cloudera Manager will incorrectly enable and disable service features based on the cluster's configured CDH version.

Change the Default Administrator Password

As soon as possible after running the wizard and beginning to use Cloudera Manager, change the default administrator password:
  1. Right-click the logged-in username at the far right of the top navigation bar and select Change Password.
  2. Enter the current password, and a new password twice and then click Update.

Test the Installation

You can test the installation following the instructions in Testing the Installation.
