> HBASE-13351 annotates Master RPCs so that RegionServer RPCs are treated with
> a higher priority compared to user RPCs (and they are handled by a separate
> set of handlers, etc.). It may be good to stretch this to users too - hbase
> superuser (configured via hbase.superuser) gets higher priority over other
> users in the RPC handling. That way the superuser can always perform
> administrative operations on the cluster even if all the normal priority
> handlers are occupied (for example, we had a situation where all the master's
> handlers were tied up with many simultaneous createTable RPC calls from
> multiple users and the master wasn't able to perform any operations initiated
> by the admin). (Discussed this some with [~enis] and [~elserj]).
> Does this make sense to others?
