Review request for Ambari, Andrew Onischuk, Sumit Mohanty, and Sebastian Toader.


Bugs: AMBARI-15531
    https://issues.apache.org/jira/browse/AMBARI-15531


Repository: ambari


Description
-------

When cluster created via blueprint the /tmp folder may be created implicitly by 
various components with permissions that prevent other components to write to 
it. In the specific case described by the linked issue, the folder has been 
created when starting the historyserver, and later on the folder couldn't be 
written by the hiveserver2. (ideally the folder is expected to be created when 
the namenode starts)

The patch fixes the specific case described in the bug, however a more 
robust/generic solution is needed to properly sort out the problem.
