[jira] [Commented] (MAPREDUCE-3854) Reinstate environment variable tests in TestMiniMRChildTask

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13205951#comment-13205951 ] 

Vinod Kumar Vavilapalli commented on MAPREDUCE-3854:
----------------------------------------------------

Short answer for the HOME issue you pointed out is - no, we aren't supporting it anymore.

With 1.0, we never fixed TaskTracker to cleanup the environment(MAPREDUCE-103), so things like HOME *needed to* be supported. In 0.23.*, it is now set by NodeManager after the ends' clean up. So, $HOME already points to the user's home dir, we shouldn't be needing it anymore.
