>
> 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.
