Long term component architecture

As the main curator of open standards in Hadoop, Cloudera has a track record of bringing new open source solutions into its platform (such as Apache Spark, Apache HBase, and Apache Parquet) that are eventually adopted by the community at large. As standards, you can build longterm architecture on these components with confidence.

 

PLEASE NOTE:

With the exception of DSSD support, Cloudera Enterprise 5.6.0 is identical to CDH 5.5.2/Cloudera Manager 5.5.3  If you do not need DSSD support, you do not need to upgrade if you are already using the latest 5.5.x release.

 

Note: All CDH and Cloudera Manager hosts that make up a logical cluster need to run on the same major OS release to be covered by Cloudera Support.

CDH 5 provides 64-bit packages for RHEL-compatible, SLES, Ubuntu, and Debian systems as listed below.

Important: Cloudera supports RHEL 7 with the following limitations:

 

Note:

  • Cloudera Enterprise is supported on platforms with Security-Enhanced Linux (SELinux) enabled. Cloudera is not responsible for policy support nor policy enforcement. If you experience issues with SELinux, contact your OS provider.
  • CDH 5.8 DataNode hosts with EMC® DSSD™ D5™ are supported by RHEL 6.6, 7.1, and 7.2.

Note:

  1. MySQL 5.5 is supported on CDH 5.1. MySQL 5.6 is supported on CDH 5.1 and higher. The InnoDB storage engine must be enabled in the MySQL server.
  2. Cloudera Manager installation fails if GTID-based replication is enabled in MySQL.
  3. PostgreSQL 9.2 is supported on CDH 5.1 and higher. PostgreSQL 9.3 is supported on CDH 5.2 and higher. PostgreSQL 9.4 is supported on CDH 5.5 and higher.
  4. For purposes of transferring data only, Sqoop 1 supports MySQL 5.0 and above, PostgreSQL 8.4 and above, Oracle 10.2 and above, Teradata 13.10 and above, and Netezza TwinFin 5.0 and above. The Sqoop metastore works only with HSQLDB (1.8.0 and higher 1.x versions; the metastore does not work with any HSQLDB 2.x versions).
  5. Derby is supported as shown in the table, but not always recommended. See the pages for individual components in the Cloudera Installation and Upgrade guide for recommendations.
  6. CDH 5 Hue requires the default MySQL version of the operating system on which it is being installed, which is usually MySQL 5.1, 5.5, or 5.6.

CDH and Cloudera Manager Supported JDK Versions

Only 64 bit JDKs from Oracle are supported. Oracle JDK 7 is supported across all versions of Cloudera Manager 5 and CDH 5. Oracle JDK 8 is supported in C5.3.x and higher.

 

A supported minor JDK release will remain supported throughout a Cloudera major release lifecycle, from the time of its addition forward, unless specifically excluded.

 

Warning: JDK 1.8u40 and JDK 1.8u60 are excluded from support. Also, the Oozie Web Console returns 500 error when Oozie server runs on JDK 8u75 or higher.

 

Running CDH nodes within the same cluster on different JDK releases is not supported. JDK release across a cluster needs to match the patch level.

  • All nodes in your cluster must run the same Oracle JDK version.
  • All services must be deployed on the same Oracle JDK version.

 

The Cloudera Manager repository is packaged with Oracle JDK 1.7.0_67 (for example) and can be automatically installed during a new installation or an upgrade.

 

For a full list of supported JDK Versions please see CDH and Cloudera Manager Supported JDK Versions.

Hue

Hue works with the two most recent versions of the following browsers. Cookies and JavaScript must be on.

  • Chrome
  • Firefox
  • Safari (not supported on Windows)
  • Internet Explorer

Hue could display in older versions and even other browsers, but you might not have access to all of its features.

Selected tab: SupportedBrowsers

CDH requires IPv4. IPv6 is not supported.

See also Configuring Network Names.

 

Multihoming CDH or Cloudera Manager is not supported outside specifically certified Cloudera partner appliances. Cloudera finds that current Hadoop architectures combined with modern network infrastructures and security practices remove the need for multihoming. Multihoming, however, is beneficial internally in appliance form factors to take advantage of high-bandwidth InfiniBand interconnects.

 

Although some subareas of the product may work with unsupported custom multihoming configurations, there are known issues with multihoming. In addition, unknown issues may arise because multihoming is not covered by our test matrix outside the Cloudera-certified partner appliances.
