> This is related to the TestSeekTo test case where the seekBefore() does not
> work with Prefix_Tree because of an issue in getFirstKeyInBlock(). In the
> trunk and branch-1 changing the return type of getFirstKeyInBlock() from BB
> to Cell resolved the problem, but the same cannot be done in 0.98. Hence we
> need a change in the KvUtil.copyToNewBuffer API to handle this. Since the
> limit is made as the position - in seekBefore when we do
> {code}
> byte[] firstKeyInCurrentBlock = Bytes.getBytes(firstKey);
> {code}
> in HFileReaderV2.seekBefore() we end up in an empty byte array and it would
> not be the expected one based on which we try to seek to load a new block.
