---------------------------------------
Summary: Add warning logs for slow ALTER_TABLE event processing
Key: IMPALA-11540
URL: https://issues.apache.org/jira/browse/IMPALA-11540
Project: IMPALA
Issue Type: Improvement
Components: Catalog
Reporter: Quanlong Huang
Assignee: Quanlong Huang
ALTER_TABLE event could trigger full refresh on the table, which is expansive
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. altering the owner
don't need to reload the file metadata.
