Review request for Ambari, Andrew Onischuk, Dmytro Sen, Sumit Mohanty, and Sid
Wagle.
Changes
-------
Added role command ordering for stopping NameNode, ZK-fc and JournalNode as
well.
Bugs: AMBARI-14657
https://issues.apache.org/jira/browse/AMBARI-14657
Repository: ambari
Description
-------
PROBLEM
On a cluster with NN HA enabled, non root Ambari user and AMS in distributed
mode, STOP ALL services command fails at AMS.
BUG
Wrong role command ordering between Journal Node and AMS caused Journal Node to
be stopped before AMS. Hence, graceful shut down of AMS HBase in distributed
mode failed. The fall back option to kill the HBase daemon also failed because
of insufficient permissions for the non root ambari user.
FIX
Fix the role command ordering and use the ambari sudo helper to give
permissions to the fallback kill command.

Testing
-------
Manual testing done to trigger both the issues (Role command ordering and Sudo)
sepearately and together.
ambari-server unit tests pass.
Submitted patch through Apache.
Java unit tests running locally.
Manual testing also done with AMS embedded mode to make sure no regression has
been caused.
Thanks,
Aravindan Vijayan
