New Features and Changes in Cloudera Director
New Features and Changes in Cloudera Director 2
What's New in Cloudera Director 2.8.0
- Simplified cluster templates. Cloudera Director now includes a simple setup procedure for launching CDH clusters, available through the UI, CLI, or API. When you create a cluster with the simple setup procedure, the installation process is streamlined because Cloudera Director selects default settings for you wherever possible. The results is fewer installation steps, and less risk of errors. You choose from a range of cluster types that are based on common CDH workloads, including basic, data engineering, analytic database, operational database, and EDH.
- Export cluster configuration files. You can now export a cluster configuration file from any running CDH cluster, which can be used as-is or with changes for launching other clusters. Sensitive information, such as cloud provider credentials and database passwords, is redacted in the exported configuration file.
- The command line client's standalone functionality has been deprecated. The standalone CLI commands will be removed in a future release (bootstrap, status, terminate, update, and validate), and the Cloudera Director client will be used only for command line interactions with a Cloudera Director server. When the validate command is removed, a new CLI command will be provided for validating a configuration file.
- Support for RHEL 7.4 and CentOS 7.4 in Azure.
- Support for AWS instance types P3 and G3.
- Support for the AWS region EU (Paris), eu-west-3.
- A number of issues have been fixed. See Issues Fixed in Cloudera Director 2.8.0 for details.
What's New in Cloudera Director 2.7.1
- A number of issues have been fixed. See Issues Fixed in Cloudera Director 2.7.1 for details.
What's New in Cloudera Director 2.7.0
- LDAP and Active Directory support for Cloudera Director users. You can now configure Cloudera Director to authenticate users against an LDAP or AD server and use groups on the server to control user roles in Cloudera Director.
- Improved Java 8 support for clusters. Cloudera Director can assume direct control of JDK installation to make it easier to install a single JDK, including Java 8, on Cloudera Manager and cluster instances.
- Instance level control of normalization. Cloudera Director previously allowed the disabling of instance normalization steps through global configuration. With Cloudera Director 2.7.0 and higher, instance template configuration can override the global configuration of those steps, so that normalization can be enabled and disabled differently for different instances.
- AWS plugin improvements:
- New EC2 instance types M5, H1, and C5 are now supported.
- A configuration file can now supply EC2 instance user data in its raw form, and Cloudera Director will base64 encode it appropriately before submitting it to EC2, so that users do not need to do the encoding themselves.
- A number of issues have been fixed. See Issues Fixed in Cloudera Director 2.7.0 for details.
What's New in Cloudera Director 2.6.1
- A number of issues have been fixed. See Issues Fixed in Cloudera Director 2.6.1 for details.

- TLS Support for Cloudera Manager: Cloudera Director is now able to communicate with Cloudera Manager 5.13 or later after it has been configured manually to communicate over TLS. See Manual TLS.
- TLS Support for Cloudera Director clients: The Java and Python client libraries and the Cloudera Director client are now able to communicate with the Cloudera Director server after the server has been configured to communicate over TLS. See TLS for Cloudera Director Itself.
- SSH Host Key Support: Cloudera Director can now retrieve SSH host keys from instances it allocates to provide extra security. See SSH Host Key Retrieval and Verification.
- Support for including Cloudera Data Science Workbench when installing CDH on AWS with a Cloudera Director configuration file.

- Simplified Azure Environment and instance template configurations. Configurations from previous releases of Cloudera Director will continue to be supported.
- Support for Azure Managed Disks. Azure Managed Disks are an improvement over Azure Storage Accounts. They simplify storage, provide better reliability for availability sets, and improve scalability. For more information on Managed Disks, see Azure Managed Disks Overview.

- Cloudera Director now supports S3Guard, which guarantees a consistent view of data stored in Amazon S3.
- Cloudera Director can now recognize changes made directly from the cloud provider console to provisioned instances such as instance type and AMI.
