> 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.
