             Summary: Blueprint Deployed Clusters Throw Exceptions On Startup
                 Key: AMBARI-16225
                 URL: https://issues.apache.org/jira/browse/AMBARI-16225
             Project: Ambari
          Issue Type: Bug

    Affects Versions: ambari-2.4.0

            Assignee: Sandor Magyari
            Priority: Critical
             Fix For: ambari-2.4.0


After deploying a cluster with standard services (ZK, HDFS, etc) using blueprints, when user restarts Ambari, there are exceptions like below as the server is starting up.

{code}
java.lang.NullPointerException

{code}

Looks like a the AMC is not initialized yet as the heartbeat from agents is being handled. It doesn't seem to affect operation of the cluster, but it looks really bad.
