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

             Summary: Hive Query log does not work when hive.exec.parallel is true
                 Key: HIVE-9120
                 URL: https://issues.apache.org/jira/browse/HIVE-9120
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2, Logging
            Reporter: Dong Chen


When hive.exec.parallel is true, the query log is not saved and Beeline can not retrieve it.
When parallel, Driver.launchTask() may run the task in a new thread if other conditions are also on. TaskRunner.start() is invoked instead of TaskRunner.runSequential(). This cause the threadlocal variable OperationLog to be null and query logs are not logged.
The OperationLog object should be set in the new thread in this case.
