             Summary: Use table id to detect uniqueness of table for drop table event
                 Key: IMPALA-9913
                 URL: https://issues.apache.org/jira/browse/IMPALA-9913
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Vihang Karajgaonkar
            Assignee: Vihang Karajgaonkar


When a DROP_TABLE event is received by the EventsProcessor, it needs to make a determination of whether the table in the cache is same as the table in the event. Without a unique id from the HMS it uses {{createTime}} field of the HMS table object to determine if the table matches with the table in the event.

Since then HMS API was enhanced to include an {{id}} field which is guaranteed to unique accross all the tables (even the past deleted tables). Instead of the using createTime we should use id field to do the matching.
