Tarek Abouzeid commented on TEZ-3894:
-------------------------------------
i am using Tez 0.9.1 and the file.out and file.out.index in prod, are being
created with different permissions
{code:java}
-rw-------. 1 hive hadoop 28 May 16 16:17 file.out
-rw-r-----. 1 hive hadoop 32 May 16 16:17 file.out.index
{code}
i am using hortonworks 3.1 , also in other environment using same version its
working fine, also checked the umask for user (tez,hive,mapred) and all set to
0022, any tips that can help solving this please ?

> Tez does not explicitly set the permissions of intermediate output files for
> shuffle. In a secure cluster the shuffle service is running as a different
> user than the task, so the output files require group readability in order to
> serve up the data during the shuffle phase. If the umask is too restrictive
> (e.g.: 077) then the task's file.out and file.out.index permissions can be
> too restrictive to allow the shuffle handler to access them.
