      Description

      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.
