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.
> MAPREDUCE Impersonation is not working in 22
