It’s official – Cloudera’s Distribution for Hadoop Version 2, which we often shorthand as CDH2, has been released. CDH2 is the product we recommend to our current production customers. It’s a stable version that has undergone a long cycle of time in the field with a variety of customers, in addition to Cloudera’s internal QA process.
And with the CDH2 release, the Cloudera engineering team is excited to start the feedback and development process for the next version of Cloudera’s Distribution for Hadoop – Version 3. CDH3 includes an Apache Pig package with additional bug fixes and performance improvements, and the Apache Hive package is now based on the latest Apache release. One of the most notable aspects of CDH3 beta 1 is what has not changed: CDH3 remains based on the Apache 0.20 release. However, we have already bundled many new improvements and bug fixes in CDH3. The release notes cover these changes in detail.
What the release notes don’t share, though, is what we plan on putting into upcoming CDH3 releases. Cloudera is working hard with the rest of the Apache community to deliver additional features in CDH3 including the following noteworthy items:
- A new Pig package based on the latest Apache release.
- Apache HBase and ZooKeeper, previously only supported as part of our contrib repository, will become first class packages in CDH3.
- The security work Yahoo! is contributing, which should significantly impact Hadoop adoption.
