--------------------------------
Summary: 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
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.
