[jira] [Created] (IMPALA-11540) Add warning logs for slow ALTER_TABLE event processing

---------------------------------------

             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.
