Release Note:

Hide
From 2.0 branch onwards KVComparator and its subclasses MetaComparator, RawBytesComparator are all deprecated.
All the comparators are moved to CellComparator. MetaCellComparator, a subclass of CellComparator, will be used to compare hbase:meta cells.
Previously exposed static instances KeyValue.COMPARATOR, KeyValue.META_COMPARATOR and KeyValue.RAW_COMPARATOR are deprecated instead use CellComparator.COMPARATOR and CellComparator.META_COMPARATOR.
Also note that there will be no RawBytesComparator. Where ever we need to compare raw bytes use Bytes.BYTES_RAWCOMPARATOR.
CellComparator will always operate on cells and its components, abstracting the fact that a cell can be backed by a single byte[] as opposed to how KVComparators were working.
