Anoop Sam John commented on HBASE-10916:
----------------------------------------
The SLG is a public interface exposed.
{code}
@InterfaceAudience.Public
@InterfaceStability.Evolving
public interface ScanLabelGenerator extends Configurable
{code}
What is ur call on changing the name now Andy?
Also we might better change the signature of the method in it considering we
will have a chain of SLGs now
{code}
public List<String> getLabels(User user, Authorizations authorizations);
{code}
be better changed to
{code}
public List<String> getAuths(User user, List<String> auths);
{code}
> [VisibilityController] Stackable ScanLabelGenerators

>
> The ScanLabelGenerator is used by the VisibilityController to assemble the
> effective label set for a user in the RPC context before processing any
> request. Currently only one implementation of this interface can be
> installed, although which implementation to use can be specified in the site
> file. Instead it should be possible to stack multiple implementations of this
> component the same way we do coprocessors, installed with explicit priority
> with ties broken by a counter, where those implementations installed later in
> the chain have an opportunity to modify the pending effective label set.
