Review request for Ambari, Dmitro Lisnichenko, Dmytro Sen, Jonathan Hurley, Nate Cole, and
Robert Levas.


Bugs: AMBARI-12150
    https://issues.apache.org/jira/browse/AMBARI-12150


Repository: ambari


Description
-------

STR:
1. Installed Ambari 2.1.0 at build 2216
2. Deployed a 5 node cluster with HDP 2.2.7 and HDFS, MR, YARN, Tez, Pig, Oozie.
3. Enabled NameNode HA and ResourceManager HA
4. Registered version 2.3.0.0-2425
5. Attempted to start RU
6. Pre Checks failed stating that services were down when they were clearly not
Note: Doing a Stop All Services and Start All remedied it. Restarting Ambari Server did not
fix it since the states in the DB are inconsistent.
There's nothing that jumps out at me in the ambari-server logs; there are error messages,
but not related.

Testing
-------

On the cluster where the issue happened, I replaced the jar file and was able to move forward.

Unit tests are in progress.


Thanks,

Alejandro Fernandez
