[jira] [Created] (TAJO-1251) Query is hanging occasionally by shuffle report

Jinho Kim created TAJO-1251:
-------------------------------

             Summary: Query is hanging occasionally by shuffle report
                 Key: TAJO-1251
                 URL: https://issues.apache.org/jira/browse/TAJO-1251
             Project: Tajo
          Issue Type: Bug
          Components: data shuffle, query master
    Affects Versions: 0.9.0
            Reporter: Jinho Kim


Currently, Query is failed when race condition occur in {{SubQuery.waitingIntermediateReport()}}. If a event is not complete, other events will be blocked in AsyncDispatcher.
We should remove the thread lock in event handler.
