------------------------------------------------
I have started making some changes to see if every where we can work with
Cells. I will check with your Iterable proposal also. Yes we need two impl of
Hash for ROW and ROWCOL. Was thinking if we can some how tie this hash func
with the bloom filter type. Thanks for the feedback.
The reference to previous cell is there even in StoreScanner#next(). So even
that may have to be solved and not only here in Bloom Filter.
> StoreFile$Writer.appendGeneralBloomFilter generates extra KV
