             Summary: Blueprints: Deploying Blueprint with Hive fails due to ordering issues
                 Key: AMBARI-8934
                 URL: https://issues.apache.org/jira/browse/AMBARI-8934
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.0.0
            Reporter: Robert Nettleton
            Assignee: Robert Nettleton
             Fix For: 2.0.0


Attempting to deploy a Blueprint that includes HIVE is currently broken.  

When the server attempts to install/startup the MYSQL_SERVER component, the following exception is logged in ambari-server.log:

03:01:16,381  INFO [qtp565252965-94] HeartBeatHandler:551 - State of service component MYSQL_SERVER of service HIVE of cluster clusterone has changed from INSTALLED to STARTED at host c6401.ambari.apache.org

Recent stack defintion refactorings in the Hive area seem to have somehow modified the ordering in which services start. In addition, the Hive "MYSQL_SERVER" component appears to startup at install time.  This triggers the ambari-server's HeartbeatHandler to set the component's state directly, which causes the above exception in the state machine code.  

I'm working on a fix for this, and will be submitting a patch shortly.
