Dong Chen created HIVE-9120:
-------------------------------
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.
