Summary: Add table id to HMS get methods
Key: HIVE-22018
URL: https://issues.apache.org/jira/browse/HIVE-22018
Project: Hive
Issue Type: Sub-task
Reporter: Daniel Dai
It is possible we remove a table and immediately move another table to occupy
the same name. CachedStore may retrieve the wrong table in this case. We shall
add tableid in every get_(table/partition) api, so we can compare the one
stored in TBLS (tableid is part of Table object) and check if the same id, if
not, HMS shall fail the read request. The initial table id can be retrieved
along with writeid (in DbTxnManager.getValidWriteIds call, to join the TBLS
table)
