Zheng Hu commented on HBASE-21206:
----------------------------------
Add some comment in the new patch.v1 to explain the corner case . As far as I
know, only when the scan.nextRaw reach the batch limit and happen to exhaust
all cells of the scan, the bug will occur... because response's result list
and moreResultsInRegion come from two scan.nextRaw, it's a inconsistent
state... Our online hbase user discovered the imcomplete cells, and we took few
days to locate the bug.....
> Scan with batch size may return incomplete cells
