Prasanth Jayachandran updated HIVE-18349:
-----------------------------------------
Attachment: HIVE-18349.7.patch
Primary/foreign keys, contraints api was inconsistent wrt to return value.
DirectSQL returned empty list vs JDO returned null. Null events are considered
failed for notification listeners that was causing TestDbNotificationListener
failure. Fixed the return value to make it consistent.
> Misc metastore changes for debuggability, error on commit txn failures

> 1) Hive metastore audit event log/metastore log does not log the final status
> (success or failed) of the event. Some operations like for example,
> drop_table returns a boolean success flag but it never gets logged anywhere.
> However the same is sent to end event listeners or other metastore event
> listeners. It will be good to log the final status of the events.
> 2) Make connection timeout when using connection pool configurable. Currently
> its hard coded to 30 seconds.
> 3) Provide a config to enable connection leak detection for HikariCP or
> enable when debug logging is enabled.
