> The initial bulk load option for Spark bulk load sends values over one by one
> through the shuffle. This is the similar to how the original MR bulk load
> worked.
> How ever the MR bulk loader have more then one bulk load option. There is a
> second option that allows for all the Column Families, Qualifiers, and Values
> or a row to be combined in the map side.
> This only works if the row is not super wide.
> But if the row is not super wide this method of sending values through the
> shuffle will reduce the data and work the shuffle has to deal with.
