Subject [jira] [Commented] (YARN-4731) Linux container executor fails to delete nmlocal folders
Date Fri, 26 Feb 2016 19:30:18 GMT

    [ https://issues.apache.org/jira/browse/YARN-4731?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15169619#comment-15169619
] 

Colin Patrick McCabe commented on YARN-4731:
--------------------------------------------
