Subject [jira] [Commented] (MAPREDUCE-3593) MAPREDUCE Impersonation is not working in 22

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3593?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13174443#comment-13174443

Mayank Bansal commented on MAPREDUCE-3593:
------------------------------------------

In Hadoop 22 when we try to submit job using proxy users, while proxy user tries to impersonate
other users based on core-site.xml configuration, It is failing due to permission issues for
the staging directory. The problem is job is submitted using proxy user, it is not able to
impersonate as the actual user.
