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

             Summary: RU - Resource Manager Service Check fails because hdfs-site.xml is missing
when host does not have NameNode component
                 Key: AMBARI-12035
                 URL: https://issues.apache.org/jira/browse/AMBARI-12035
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server

            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
            Priority: Blocker
             Fix For: 2.1.0


STR:

* Deploy cluster with HDP 2.2 and HDFS, YARN, RM, ZK
* On the hosts with RM, make sure that there is no NameNode
* Enable NameNode HA, and RM HA
* Register HDP 2.3
* Start a long running job
* Perform an RU, which will fail because the RM hosts will not have hdfs-site in its config
folder /etc/hadoop/2.3.0.0-2800/0
