Andrew Purtell created HBASE-7254:
-------------------------------------
Summary: Use new Globally Barriered Procedure mechanism to replace
AccessController ZK-mediated permissions cache
Key: HBASE-7254
URL: https://issues.apache.org/jira/browse/HBASE-7254
Project: HBase
Issue Type: Task
Components: Coprocessors, security
Affects Versions: 0.96.0
Reporter: Andrew Purtell
Assignee: Andrew Purtell
After HBASE-7212 goes in, we could tighten up the permissions cache using a
barrier for grant and revoke ops. We should consider replacing the current ZK
watcher based permissions cache "RPC via ZK" with this Procedure mechanism that
provides much the same, but with the added benefit that we can fail the grant
or revoke op if one or more RSes fail to ack the update.
