> Improve SQLOperation log handling when cleanup

> Key: HIVE-23727
> URL: https://issues.apache.org/jira/browse/HIVE-23727
> Project: Hive
> Issue Type: Improvement
> Reporter: Zhihua Deng
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The SQLOperation checks _if (shouldRunAsync() && state !=
> OperationState.CANCELED && state != OperationState.TIMEDOUT)_ to cancel the
> background task. If true, the state should not be OperationState.CANCELED, so
> logging under the state == OperationState.CANCELED should never happen.
