------------------------------------------------
bq.Shouldn't this be unsupportedoperationexception in your new key only class?
For the value part we can throw UnSupportedException but for the Tag part we
cannot because in the latest comparisons we do we also compare the seqid added
during WAL replay which is inside a tag. So to find an exact key we may end up
comparing the tag with seqid also.
> Revisit how the key byte[] is passed to HFileScanner.seekTo and reseekTo

> Currently the byte[] key passed to HFileScanner.seekTo and
> HFileScanner.reseekTo, is a combination of row, cf, qual, type and ts. And
> the caller forms this by using kv.getBuffer, which is actually deprecated.
> So see how this can be achieved considering kv.getBuffer is removed.
