As Hadoop is becoming a key back-end datacenter application, good Hadoop support matters. It makes for a fantastic performance and stress test. We would strongly encourage anyone who produces a JVM/JDK to test compiling and running Hadoop with it. A request for help from JVM/JDK developers

Hadoop has been used on JRockit, though not at 'production' scale.ДЄnyone who has information about compatibility of Hadoop 2.x with IBM JDK is encouraged to edit this wiki.ДЄn older version of Hadoop (0.20.2) has been tested comprehensively and works with IBM Java 6 SR 8. The most notable changes in the release were: HotSpot JVM included (the HotSpot JVM was first released in April 1999 for the J2SE 1.2 JVM). Oracle's JRockit JVM is not the same as the Sun JVM: it has very different heap and memory management behavior. OpenJDK has been used to qualify Hadoop 2.2 and the rest of the Hortonworks bundle on RHEL6. Useful tips for discovering and inspecting Sun JVM confuguration flags are in the following blog post: inspecting-hotspot-jvm-options OpenJDK 7 Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 21 and earlier, 6 Update 45 and earlier, and 5.0 Update 45 and earlier, and OpenJDK 7, allows remote attackers to affect confidentiality, integrity, and availability via vectors related to AWT.

It is the default in 1.6.0_24 and above on 64 bit JVMs, and appears now to be stable. Several have reported success using it on 1.6.0_21 and above. This feature was first introduced in 1.6.0_14 but problems were been reported with its use on versions prior to 1.6.0_20. Using the Compressed Object References JVM feature (-XX:+UseCompressedOops) reduces memory consumed and increases performance on 64 bit Sun JVMs. The workers can be set up for either 32-bit or 64-bit operation, depending upon preferences and how much memory the individual tasks need. In a large cluster the NameNode and JobTracker need to run in 64-bit mode to keep all their data structures in memory. Hortonworks has certified openjdk 1.7.0_09-icedtea on RHEL6 with Hadoop 2.2.0, HBase 0.96, Pig, Hive, HCatalog, Oozie, Sqoop, and Ambari.
