Subject [jira] [Commented] (AMBARI-575) Datanode/tasktracker process should be able to be run in 64-bit mode.
Date Fri, 29 Jun 2012 18:39:45 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13404106#comment-13404106

Hitesh Shah commented on AMBARI-575:
------------------------------------

Part of this was addressed in AMBARI-580. However, a full code cleanup is still needed to
support:
 
1) a full 64-only cluster ( should not need jdk32 anymore)
2) a full 32-bit only
3) a mixed approach if performance tests show that 32-bit DN/TTs are a must in critical production
environments with the latest version of jdk-1.6.0u31

> As mentioned in AMBARI-546, it may not be necessary to run the processes in 32-bit mode
given the fixes in jdk ( post 1.6.0u23 ). Given that AMBARI already requires u26, it might
be good to introduce a tunable option to run the processes in 64-bit mode.
