[jira] Commented: (MAPREDUCE-1085) For tasks, "ulimit -v -1" is being run when user doesn't specify mapred.child.ulimit

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1085?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12763860#action_12763860 ] 

Ravi Gummadi commented on MAPREDUCE-1085:
-----------------------------------------

We can check if the value is positive or not and add the ulimit command only if needed.

> For tasks, "ulimit -v -1" is being run when user doesn't specify mapred.child.ulimit.  Taking -1 as default value and using it in building the command is not right.
