Yong Zhang commented on HBASE-15315:
------------------------------------

Thanks comments of [~eclark] and [~enis], I just view the code of HBASE-15177 
and HBASE-15295 to find most of client call method has been add RpcController. 
This JIRA will just remove the super user being high priority as  [~eclark]'s 
suggestion. I will update the title and description.

> PriorityFunction.getPriority should consider more about admin/master call and 
> user call

> Current implementation set superuser call as ADMIN_QOS, but we have many 
> customers use superuser to normal such as put, get data, and if client put 
> much data during region assignment, RPC from HMaster may timeout because of 
> no handle. so it is better to split the admin/master call and user normal 
> call with data operation.
