Change subject: IMPALA-11540: Add logs for ALTER_TABLE events that trigger slow metadata reload ...................................................................... IMPALA-11540: Add logs for ALTER_TABLE events that trigger slow metadata reload ALTER_TABLE event could trigger full refresh on the table, which is time consuming and can lead to event-processor lagging behind. We need logs to show the difference between the before and after hmsTables so we can further distinguish the cases that actully don't need a full table refresh, e.g. changing the owner, changing tblproperties, etc. Tests: - Attach the process using IntelliJ to pause the metadata loading for a while. So the metadata reloading of ALTER_TABLE event can exceed the threshold. Manually verified the logs.
