bq. I suggest revering the change in master branch as any way it is not useful 
and needed. For other branches, I also suggest adding the addendum

Ok [~anoop.hbase] - doing that now

> In ProtobufUtil, the protobuf fields are copied into an array using 
> toByteArray().  These are then passed into the KeyValue constructor which 
> does another copy.
> It seems like we can avoid a copy here by using 
> HBaseZeroCopyByteString#zeroCopyGetBytes() ?
