Ashutosh Chauhan commented on HIVE-3255:
----------------------------------------
A WIP patch is available for review on https://reviews.facebook.net/D4113 in
case some one wants to provide a feedback on design. Some function bodies are
not done yet, but those are mostly self contained and shouldn't hinder in
design review.
> Add DBTokenStore to store Delegation Tokens in DB

> Key: HIVE-3255
> URL: https://issues.apache.org/jira/browse/HIVE-3255
> Project: Hive
> Issue Type: New Feature
> Components: Metastore, Security
> Affects Versions: 0.9.0, 0.10.0
> Reporter: Ashutosh Chauhan
> Assignee: Ashutosh Chauhan
>
> 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.
