Anoop Sam John commented on HBASE-13916:
----------------------------------------

bq.What did you think of an nio package? Seems like we have enough ByteBuffering classes to
give it substance now.
Fine. I will add the package and move the MBB class to there.  Moving in other classes can
be done as part of another cleanup jira. (Else the patch will be unnecessarily look bigger)

> This is an aggregation of N ByteBuffers. The block when served directly by block cache
buckets memory, we have the block data split across multiple byte buffers. This aggregate
type (like ByteBuffer) will serve the HFileBlock data.
> This jira wil just provide the new data structure
