> As shown above, when an HFile which has a DIFF encoding is bulkloaded into a
> splitted region whose CF's DATA_BLOCK_ENCODING is NONE, the two new HFiles
> would have inconsistent encodings.
> Besides, it would be OK if splitting region's DATA_BLOCK_ENCODING is DIFF and
> bulk loaded HFile has NONE, because the initial bulkloaded HFile would not
> write the encoding info into its meta (NoOpDataBlockEncoder.saveMetadata() is
> empty), and It then would not rewrite encoding in two generated Files in
> copyHFileHalf(). Two new HFiles' meta info would be consistent with their
> block headers, which would all be DIFF. So, no Exception would be thrown when
> scanning these files.
