Review request for Ambari, Alexander Denissov, Alejandro Fernandez, jun aoki, Jayush Luniya, Matt, and Oleksandr Diachenko. Bugs: AMBARI-15849 https://issues.apache.org/jira/browse/AMBARI-15849 Repository: ambari Description ------- Activate HAWQ standby wizard fails to delete previous hawq standby master. Currently, HAWQ standby status check is done based on the pid available in a directory. This directory is same for HAWQ master and HAWQ standby, thus if standby has been activated to active master, status of HAWQ Standby component still relies on the file and states it as running, and when an attempt is made to remove the standby component, it fails. Fixed the hawq component status derivation logic in this patch.
