> 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.
