Guangxu Cheng commented on HBASE-23237:
---------------------------------------
Hi, sir. In HBASE-20626, we use "totalRowActionRequestCount" instead of
"totalRequestCount" to calculate RPS.
When the region is moved, the QPS may have a negative number. Because the value
of "totalRowActionRequestCount" is sum of the request count of all regions on
this RegionServer. When the region is moved to other RegionServer, the current
value of "totalRowActionRequestCount" may be smaller than the last time.
