Anoop Sam John commented on HBASE-14188:
----------------------------------------
Patch LGTM
getNextCellStartPosition -> Now it is not returning the next cell's start pos. It is returning cur cell serialization size in the HFile.. Pls change the method name accordingly. Can fix on commit.

> This subtask deals with some improvments that can be done in the read path (scans) after the changes for HBASE-11425 went in.
> -> Avoid CellUtil.setSequenceId in hot path.
> -> Use BBUtils in the MultibyteBuff.
> -> Use ByteBuff.skip() API in HFileReader rather than MultiByteBuff.position().
