> MAPREDUCE-5357 does a fileystem chown() operation. chown() is not valid
> unless you are superuser. if you a chown() to yourself is a NOP, that is why
> has not been detected in Hadoop testcases where user is running as itself.
> However, in distcp testcases run by Oozie which use test users/groups from
> UGI for minicluster it is failing because of this chown() either because the
> test user does not exist of because the current use does not have privileges
> to do a chown().
> We should revert MAPREDUCE-5357. Windows should handle this with some
> conditional logic used only when running in Windows.
> Opening a new JIRA and not reverting directly because MAPREDUCE-5357 went in
> 2.1.0-beta.
