-------------------------------------------
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.
