[jira] [Commented] (AMBARI-14529) Add PXF to additional NAMENODE
which gets added when NN HA is enabled
[ https://issues.apache.org/jira/browse/AMBARI-14529?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15076246#comment-15076246 ]
Matt commented on AMBARI-14529:
-------------------------------
There are no tests for NN HA wizard step9_controller and rollback_controller, hence no additional tests for these files were added.

> 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
