Siddharth Wagle created AMBARI-1465:
---------------------------------------

             Summary: Minimize Read and Write locks for createHosts
                 Key: AMBARI-1465
                 URL: https://issues.apache.org/jira/browse/AMBARI-1465
             Project: Ambari
          Issue Type: Bug
          Components: controller
    Affects Versions: 1.2.2
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 1.3.0


Invocation count and exec time for ClustersImpl.mapHostToCluser very high

org.apache.ambari.server.state.cluster.ClustersImpl.mapHostToCluster(String, String) 
Time(ms): 252,925 
Avg Time(ms): 5,269 
Own Time(ms): 211
Invocation Count: 48

Each time host is mapped to cluster we refresh the entity manager. This results in the createHosts
call taking excess of 10 minutes
