Chia-Ping Tsai commented on HBASE-18368:
----------------------------------------
bq. We shouldn't return NEXT_ROW when FamilyFilter doesn't match.
I copy the explanation from HBASE-13122.
{noformat}
NEXT_ROW can work is because there is regionscanner and store scanner, next_row
affect store scanner.
When one storescanner switch to next row, the region scanner switch to the next
storescanner, the second store scanner will continue check the current row.
That why the change can be more efficiency.
