Review request for Ambari and Vitalyi Brodetskyi.


Bugs: AMBARI-14811
    https://issues.apache.org/jira/browse/AMBARI-14811


Repository: ambari


Description
-------

Live cluster - <http://172.22.95.30:8080/>

This is probably an infrastructure issue (or RE) but not sure yet

**Steps:**

  1. Install Dal M20 cluster with Ambari 2.2.1
  2. Register HDP 2.4.0.0-137 build
  3. Start package installation

Result:  
Observed below error during package installation ONLY on Ambari server host. A
retry of the operation resulted in same result

When I manually changed the permission of
/var/cache/yum/x86_64/6/AMBARI.2.2.1-2.x/repomd.xml file to 777 and retry,
package installation was successful on Ambari server host

Note - This issue was not seen in last run on Cent OS6
