> PhoenixAccessController should use AccessChecker instead of
> AccessControlClient for permission checks.
> In HBase, every RegionServer's AccessController maintains a local cache of
> permissions. At startup time they are initialized from the ACL table.
> Whenever the ACL table is changed (via grant or revoke) the AC on the ACL
> table "broadcasts" the change via zookeeper, which updates the cache. This is
> performed and managed by TableAuthManager but is exposed as API by
> AccessChecker. AccessChecker is the result of a refactor that was committed
> as far back as branch-1.4 I believe.
> Phoenix implements its own access controller and is using the client API
> AccessControlClient instead. AccessControlClient does not cache nor use the
> ZK-based cache update mechanism, because it is designed for client side use.
> The use of AccessControlClient instead of AccessChecker is not scalable.
> Every permissions check will trigger a remote RPC to the ACL table, which is
> generally going to be a single region hosted on a single RegionServer.
