[HCATALOG-309] HBase Revision Manager Service

• Type: Improvement
• Status: Reopened
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 0.4
• Component/s: hbase, storage handlers

Description

Implement the existing revision manager component as HBase coprocessor endpoint. This will address following security issues:

Authorization: Coprocessor has access to the HBase ACL info and can use the same to authorize client access w/o relying on ZooKeper ACLs (difficult to maintain).

Write access to ZK for RM data will be limited to the HBase region servers vs. all clients using the storage driver (clients will only need ZK read access for HBase).
