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 that happend before invalidate query will be ignored without
removing the table from cache.
Note: Also removed an unnecessary RPC call to HMS to get table object
since we alrady have required info in table metadata rpc call.
Testing:
- Added an end-to-end test to verify that drop table event happened
before time shouldn't remove the metadata object from cache.
