[jira] [Created] (HIVE-10093) Unnecessary HMSHandler initialization for default MemoryTokenStore on HS2

Szehon Ho created HIVE-10093:
--------------------------------

             Summary: Unnecessary HMSHandler initialization for default MemoryTokenStore on HS2
                 Key: HIVE-10093
                 URL: https://issues.apache.org/jira/browse/HIVE-10093
             Project: Hive
          Issue Type: Bug
            Reporter: Szehon Ho
            Priority: Minor


When the HiveAuthFactory is constructed in HS2, it initializes a HMSHandler unnecessarily right before the call to: HadoopThriftAuthBridge.startDelegationTokenSecretManager().  If the DelegationTokenStore is configured to be a memoryTokenStore, this step is not needed.

Side effect is creation of useless derby database file on HS2, causing confusion.  This could potentially be skipped if MemoryTokenStore is used.
