[jira] [Resolved] (MAPREDUCE-444) Job should be able to specify whether task vm is 32 or 64 bit

     [ https://issues.apache.org/jira/browse/MAPREDUCE-444?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Harsh J resolved MAPREDUCE-444.
-------------------------------

    Resolution: Not A Problem

Could be done with child opts/etc. I think. Closing out since this has not seen any demand nor does it appear to be useful from my experience.

> Perhaps a job should be able to specify whether it wants it's task VM's to be 32 or 64 bit.  This could be accomplished by the -d32 and -d64 java options when the task VM is exec'd.  This becomes important for native libs.
