Download CDH 5.7.5
Get the most out of your data with CDH
The world's most popular Hadoop platform, CDH is Cloudera’s 100% open source platform that includes the Hadoop ecosystem.
Built entirely on open standards, CDH features all the leading components to store, process, discover, model, and serve unlimited data.
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:
- 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.
- Cloudera Manager installation fails if GTID-based replication is enabled in MySQL.
- 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.
- 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).
- 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.
- 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.

Supported JDK Versions
Important: JDK 1.6 is not supported on any CDH 5 release (even though the libraries of CDH 5.0-CDH 5.4 are compatible). Applications using CDH libraries must run a supported version of JDK 1.7 or higher, and one that also matches the JDK version of your CDH cluster.
CDH 5.7.x is supported with the versions shown in the following table:
| Minimum Supported Version | Recommended Version | Exceptions |
|---|---|---|
| 1.7.0_55 | 1.7.0_67, 1.7.0_75, 1.7.0_80 | None |
| 1.8.0_31 | 1.8.0_60 | Cloudera recommends that you not use JDK 1.8.0_40. |
