Andrew Purtell updated HBASE-22937:
-----------------------------------
Fix Version/s: 1.3.6
> The RawBytesComparator in branch-1 have wrong comparison order
> --------------------------------------------------------------
>
> Key: HBASE-22937
> URL: https://issues.apache.org/jira/browse/HBASE-22937
> Project: HBase
> Issue Type: Bug
> Reporter: Zheng Hu
> Assignee: Zheng Hu
> Priority: Major
> Fix For: 1.5.0, 1.3.6, 1.4.11
>
>
> When digging the HBASE-22862, we found a bug in
> RawBytesComparator#compareOnlyKeyPortion (although it's unrelated to the
> corruption in HBASE-22862).
> {code}
> @Override
> @VisibleForTesting
> public int compareOnlyKeyPortion(Cell left, Cell right) {
> // ...
> return (0xff & left.getTypeByte()) - (0xff & right.getTypeByte());
> }
> {code}
> Here should be (0xff & right.getTypeByte()) - (0xff & left.getTypeByte()) I
> think.
> I can see the BloomFilter or HFile v2 are still using the comparator in
> branch-1 (but not in branch-2). Maybe we can just remove the class (if some
> HFile encoded with this comparator, then mapping to the correct KVComparator
> just like 2.x), or fix the bug in current RawBytesComparator.
