Subject [jira] [Created] (HIVE-3255) Add DBTokenStore to store Delegation Tokens in DB
Date Thu, 12 Jul 2012 21:38:34 GMT
Ashutosh Chauhan created HIVE-3255:

             Summary: Add DBTokenStore to store Delegation Tokens in DB
                 Key: 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.
