Subject [jira] [Created] (HIVE-12270) Add DBTokenStore support to HS2 delegation token
Date Tue, 27 Oct 2015 03:16:27 GMT
Chaoyu Tang created HIVE-12270:

             Summary: Add DBTokenStore support to HS2 delegation token
                 Key: HIVE-12270
             Project: Hive
          Issue Type: New Feature
            Reporter: Chaoyu Tang
            Assignee: Chaoyu Tang

DBTokenStore was initially introduced by HIVE-3255 in Hive-0.12 and it is mainly for HMS delegation
token. Later in Hive-0.13, the HS2 delegation token support was introduced by HIVE-5155 but
it used MemoryTokenStore as token store. That the HIVE-9622 uses the shared RawStore (or HMSHandler)
to access the token/keys information in HMS DB directly from HS2 seems not the right approach
to support DBTokenStore in HS2. I think we should use HiveMetaStoreClient in HS2 instead.
