> 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.
