[jira] Commented: (HADOOP-3431) hadoop streaming should kill all children processes on task failure

    [ https://issues.apache.org/jira/browse/HADOOP-3431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598780#action_12598780 ] 

lohit vijayarenu commented on HADOOP-3431:
------------------------------------------

+1. There are few side effects seen if the child processes are not killed. Eg HADOOP-2427 might be due to that, but never got a chance to confirm that.
