Review request for Ambari and Vitalyi Brodetskyi.


Bugs: AMBARI-14718
    https://issues.apache.org/jira/browse/AMBARI-14718


Repository: ambari


Description
-------

On my hcube cluster what i am seeing is /tmp gets owned by hbase:hadoop. This
is causing services like sssd to fail as /tmp is not owned by root. sssd is a
service that we recommend users setup if they want to sync up with AD. With
this service failing users are unable to login using AD credentials.

Here is the corresponding log

    
          owner = params.hbase_user,
          group = params.user_group,
