> 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.
