chaudhary, Jaimin Jetly, jun aoki, Lav Jain, Newton Alex, Oleksandr Diachenko, and Yusaku
Sako.


Changes

Reduced length of message that appears on the UI.


Bugs: AMBARI-14529
    https://issues.apache.org/jira/browse/AMBARI-14529


Repository: ambari


Description
-------

For optimal performance, PXF has to be co-located with NAMENODE and DATANODE. Stack advisor
takes care of recommending PXF to be placed on the same host which has NAMENODE and/or DATANODE.

This JIRA would take care of the following scenario.
- A cluster with PXF service installed exists.
- NN HA is enabled - a new NAMENODE is installed on a host specified by the user.
- If PXF does not exist on that host, install PXF component on that host
