------------------------------------------------
So while moving over to Cell - in all the Mappers we can allow Cell but can we
safely assume that every cell is of type Extendedcell and so we can set up the
mapper output class type to be of ExtendedCell? ExtendedCell has all the APIs
for write(), getSerializedSize() etc. If we don't do this this we are have to
again convert the cell to KV. Thoughts??
> Deprecate KV Usage in MR to move to Cells in 3.0
