Mikhail Antonov commented on HBASE-13351:
-----------------------------------------

I've included it in the patch for superusers QoS already :) but since that 
wasn't committed yet, this change doesn't help tests in this jira.

> Annotate internal MasterRpcServices methods with admin priority

> HBASE-12071, among other things, introduced annotating RPC methods to give 
> certain methods priority over others. Namely, this helps ensure that client 
> requests cannot starve out internal RPC between master and regionserver.
> Similarly, we can do the same thing for Master RPC methods that are invoked 
> by RS's.
