> HBASE-21643 introduced two new coprocessor methods postIncrementBeforeWAL and postAppendBeforeWAL instead of the old coprocessor postMutationsBeforeWAL. These coprocessor methods give coprocessors to update the new cells before apply to WAL or memstore. But the cell's column family may be changed, too. So it should apply the new cell to memstore depend on the cell's column family.
