   And, Hive.getPartitions will cause MetaStoreClient close connection.
   Similar issue: https://issues.apache.org/jira/browse/SPARK-29409
   
   The chain of method calls is as follows:
   Hive.getPartitions -> Hive.getUserName -> 
SessionState.getUserFromAuthenticator -> SessionState.get().getAuthenticator -> 
SessionState.setupAuth -> SessionState.setAuthorizerV2Config -> Hive.get -> 
Hive.getInternal -> Hive.create -> Hive.close -> metaStoreClient.close
