> Project: HBase
> Issue Type: Bug

> In StoreScanner.next(List<KeyValue>, int, String) I find this code:
> {code}
> // Check that the heap gives us KVs in an increasing order.
> if (prevKV != null && comparator != null
> && comparator.compare(prevKV, kv) > 0) {
> throw new IOException("Key " + prevKV + " followed by a " +
> "smaller key " + kv + " in cf " + store);
> }
> prevKV = kv;
> {code}
> So this checks for bugs in the HFiles or the scanner code. It needs to
> compare each KVs with its predecessor. This seems unnecessary now, I propose
> that we remove this.
