IMPALA-8823: DROP TABLE support for insert-only ACID tables
Enhances Impala to be able to drop insert-only transactional tables.
In order to do this Impala acquires an exclusive table lock in HMS
before performing the drop operation and releases the lock once
dropping the table finished.
INSERT statement does the locking and heartbeating on coordinator
side but for DROP TABLE all of these are done from Catalog side. This
means that alongside Impala coordinators now Catalog also does
heartbeating towards HMS.
Testing:
- E2E test: Dropped a table, re-created it and dropped again to
check if no locks remained in HMS.
- E2E test: After dropping a table from Impala checked if Hive also
sees it being dropped.
- Manual test: With a hacked Impala that runs a drop table long
enough I checked that there is a table lock entry in HMS during the
execution and disappears once the query finishes.
