Elliott Clark commented on HBASE-15315:
---------------------------------------
AnnotationReadingPriorityFunction will already take care of priority for all
calls to any system table, meta included. Additionally the client has been able
to tag requests as high priority for a while, so that should be done for all
calls to any system table (see PayloadCarryingRpcController.setPriority).
> 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.
