[jira] [Created] (HBASE-22333) move certain internal RPCs to high priority level

Sergey Shelukhin created HBASE-22333:
----------------------------------------

             Summary: move certain internal RPCs to high priority level
                 Key: HBASE-22333
                 URL: https://issues.apache.org/jira/browse/HBASE-22333
             Project: HBase
          Issue Type: Bug
            Reporter: Sergey Shelukhin


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).
