Doroszlai, Attila created AMBARI-19629:
------------------------------------------

             Summary: Move schemaTool invocation out of configure() to hive_metastore start()
                 Key: AMBARI-19629
                 URL: https://issues.apache.org/jira/browse/AMBARI-19629
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.5.0
            Reporter: Doroszlai, Attila
            Assignee: Doroszlai, Attila
             Fix For: 3.0.0, 2.5.0


The {{schemaTool}} invocation should not be part of the {{configure}} method as generally
the {{configure}} method should be callable from {{install}} as well and {{schemaTool}}  requires
a running database to be available which is not true if the default {{mysql}} database server
shipped with {{hive}} is used.

Also since only one component can {{configure}} method at a time on the same host in order
to avoid overwriting common shared configs the {{configure}} methods are synchronized across
all components on a host. Having the {{schemaTool}} lengthy operation in the {{configure}}
method will delay the execution of {{configure}} methods of the other components in case of
parallel command execution.
