> User calls can inadvertently DDoS master (and potentially RS), causing issues (e.g. CallQueueTooBig) for important system calls like reportRegionStateTransition.
> These calls should be moved to high pri level... I wonder if all the low-volume internal calls (i.e. except heartbeats and maybe WAL splitting stuff) should have higher pri (e.g. 20 QoS in HConstants).
