>             Project: HBase

>         // output to writer:
>         for (Cell c : cells) {
>           if (cleanSeqId && c.getSequenceId() <= smallestReadPoint) {
>             CellUtil.setSequenceId(c, 0);

>           writer.append(c);
>         }
>         cells.clear();
>       } while (hasMore);
> scanner.next will choose at most "hbase.hstore.compaction.kv.max" kvs, the last cell
still reference by StoreScanner.prevCell, so if cleanSeqId is called when the scanner.next
call StoreScanner.checkScanOrder may throw exception and cause regionserver down.
