Review request for Ambari and Andrew Onischuk.

Bugs: AMBARI-13616

Repository: ambari


As part AMBARI-13421 the role command order has been changed to ensure the ranger admin is
started before any other services that may use it on the same host. With this change some
of the old role command order dependencies were incorrectly overridden thus causing HiveSever
(and potentially others) to fail starting when cluster is deployed through UI wizard.
The ranger role command ordering has to be accommodated in such way that it doesn't break
the original dependencies.

Diffs (updated)

  ambari-server/src/main/resources/stacks/HDP/2.2/role_command_order.json 3beed16 
  ambari-server/src/test/java/org/apache/ambari/server/stack/ 6a13ab2



Manual testing:

1. Tested changes with deploying a 3 node cluster (HDP-2.3: HDFS + Zookeeper) using the Wizzard
and than enabling Namenode HA
2. Tested the same scenario as #1 but this time with Hive service included as well
3. Deploying Ranger using Blueprint
