Subject [jira] [Commented] (HIVE-3255) Add DBTokenStore to store Delegation Tokens in DB
Date Thu, 12 Jul 2012 23:39:35 GMT


Ashutosh Chauhan commented on HIVE-3255:

A WIP patch is available for review on 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.

> 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.
