Devaraj Das commented on HBASE-13375:
-------------------------------------
I am wondering if we should just handle the RegionServer rpcs this way as well
(and avoid the annotations for now, HBASE-13351)? Two classes of users gets
elevated priority at the master - the user regionservers runs as, and the
superuser (in deployments i have seen, the two are the same). Thoughts?
> Provide HBase superuser higher priority over other users in the RPC handling

> 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?
