Change subject: IMPALA-12712: Invalidate metadata on table should set better createEventId ...................................................................... IMPALA-12712: Invalidate metadata on table should set better createEventId "INVALIDATE METADATA <table>" can be used to bring up a table in Impala's catalog cache if the table exists in HMS. Currently, createEventId for such tables are always set as -1 which will lead to always removing the table. Sequence of drop table + create table + invalidate table can lead to flaky test failures like IMPALA-12266. Solution: When Invalidate metadata <table> is fired, fetch the latest eventId from HMS and set it as createEventId for the table, so that drop table event happend before invalidate query will be ignored without removing the table from cache. Testing: - Added an end-to-end test to verify that drop table event happened before time shouldn't remove the metadata object from cache.
