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. -- This message is automatically generated by JIRA.
