----------------------------------

             Summary: RU: Alter service check order
                 Key: AMBARI-12863
                 URL: https://issues.apache.org/jira/browse/AMBARI-12863
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
            Reporter: Nate Cole
            Assignee: Nate Cole
            Priority: Critical
             Fix For: 2.1.2


HBase service check failed consistently because the HBase Master died as it was trying to
write the WAL and could not find enough good datanodes.  The service check for HBase was run
before the service check for HDFS.  There may be a situation in which we're not giving enough
time for all the DN's to come up before the HBase service check is being performed, and if
it would make more sense to service check HDFS before we service check HBase due to dependencies.

With that said it feels like the RU service check order should be:
* ZooKeeper
* HDFS
* YARN
* Everything else
