ramkrishna.s.vasudevan commented on HBASE-14921:
------------------------------------------------

bq. to move on to CellChunkMap (the real thing).
Ya fine to move to this. We have made necessary changes to avoid copy to get the chunk id.
This change and the chunkId creation  can be committed as seperate patches. You can create
the CellChunkMap based on that.
