Review request for Ambari, Alejandro Fernandez, Jaimin Jetly, jun aoki, Jayush Luniya, Oleksandr
Diachenko, Richard Zang, and Sumit Mohanty.


Removed NodeManager, Datanode and Namenode start dependency from HAWQSTANDBY, as HAWQ STANDBY
is dependent on HAWQ MASTER. And HAWQ MASTER is dependent on the required services.

Bugs: AMBARI-14733

Repository: ambari


This small patch address AMBARI-14733.

HAWQ Service check should be executed after HAWQMASTER, HAWQSTANDBY and HAWQSEGMENT have started.

However, currently HAWQ SERVICE CHECK has no dependency on HAWQSEGMENT start, thus it gets
scheduled before starting HAWQSEGMENT causing the deploy to fail.

Diffs (updated)

  ambari-server/src/main/resources/stacks/HDP/2.3/role_command_order.json 1b6eefc 



Yes manual.
