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

             Summary: Hadoop2: NodeManager requiring MR2 client
                 Key: AMBARI-2843
                 URL: https://issues.apache.org/jira/browse/AMBARI-2843
             Project: Ambari
          Issue Type: Task
          Components: agent
            Reporter: Nate Cole
            Assignee: Nate Cole
             Fix For: 1.4.0


When installing a NodeManager to a host that has no other YARN or MR2 components, NodeManager
fails startup with the error below.  Installing 
{{hadoop-mapreduce}} allows NM to startup.
