Change subject: IMPALA-12529: Show logs for the time of acquiring table/db locks ...................................................................... IMPALA-12529: Show logs for the time of acquiring table/db locks Waiting for table locks could take long when there are lots of concurrent catalog operations, e.g. DDL/DMLs or HMS events processing, on the same table. It'd be helpful to show the time of acquiring table locks in logs for better diagnostics. We already have TRACE level logs for acquiring the table/db locks. This changes them to WARN level when the duration exceeds a threshold (100ms). Ran a GVO without the threshold and found most of the duration are under 100ms. The majority is 0ms. So choose 100ms to just show abnormal locking.
