------------------------------------------
Summary: get_token thrift call fails for DBTokenStore in remote
HMS mode
Key: HIVE-17659
URL: https://issues.apache.org/jira/browse/HIVE-17659
Project: Hive
Issue Type: Bug
Components: Metastore
Reporter: Vihang Karajgaonkar
Assignee: Vihang Karajgaonkar
The {{get_token(String tokenIdentifier)}} HMS thrift API fails when HMS is
deployed in remote mode and when there is no token found with that
tokenIndentifier. This could happen when an application calls a
renewDelegationToken on an expired/cancelled delegation token. The issue is
that get_token tries to return a null result values which cannot be done in
Thrift. The API call errors out with {{org.apache.thrift.TApplicationException
unknown result}} exception which is uncaught and HS2 thrift server closes the
client transport. So no further calls from that connection can be accepted
unless client reconnects to HS2 again.
