Review request for Ambari, Alexander Denissov, bhuvnesh chaudhary, Goutam Tadi, jun aoki,
Lav Jain, and Newton Alex.


Bugs: AMBARI-15215
    https://issues.apache.org/jira/browse/AMBARI-15215


Repository: ambari


Description
-------

*On Assign Masters:*
HAWQ Master and HAWQ Standby Master cannot be deployed on the same host.

*On Assign Clients:*
PXF must be installed on the NameNode, Standby NameNode and all the DataNodes. The following
<n> host(s) do not satisfy the colocation recommendation: <list of hostnames>

HAWQ Segment must be installed on all the DataNodes. The following <n> host(s) do not
satisfy the colocation recommendation: <list of hostnames>

*On Configuration Validation:*
The default Postgres port (5432) on the Ambari Server conflicts with the default HAWQ Master
port. If you are using port 5432 for Postgres, you must either deploy the HAWQ Master on a
different host or configure a different port for the HAWQ Master in the HAWQ Configuration
page.
