> 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
> Assignee: Aihua Xu
> Priority: Minor
> Attachments: HIVE-10093.patch
>
>
> 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 HiveServer2 in
> secure clusters, causing confusion. This could potentially be skipped if
> MemoryTokenStore is used.
