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

             Summary: Set datanucleus.autoCreateSchema=false for Hive to allow parallel start
for HiveServer2 and Hive Metastore
                 Key: AMBARI-10983
                 URL: https://issues.apache.org/jira/browse/AMBARI-10983
             Project: Ambari
          Issue Type: Bug
          Components: stacks
    Affects Versions: 2.1.0
            Reporter: Sumit Mohanty
            Assignee: Sumit Mohanty
             Fix For: 2.1.0


After enabling parallel task execution, it is noticed that {{hive --config /usr/hdp/current/hive-server2/conf/conf.server
--service metatool -listFSRoot}} hangs. This could be due to

one possible cause is when we start hive-server2, Hive detect some table is missing and auto-create
table, but in the meantime, schematool is creating tables, which leads to unpredicted result.
Try to disable auto-create table, and start hive-server2 after schematool.
