> Before HIVE-1696 metastore was completely stateless and all the data is in backend db.
HIVE-1696 added delegation tokens for metastore which metastore needs to keep in memory. HIVE-2467
added support for storing delegation tokens in ZooKeeper via an interface {{DelegationTokenStore}}.
This jira is about using DB backend for storing tokens which metastore uses for storing data.
