> In the buildRow() of HBaseRelation, CellUtil.cloneValue will already create a 
> copy of the data. If the data type is BinaryType, another copy is being made 
> within Utils.hbaseFieldToScalaType in Utils.scala. Generally, binary data can 
> be fairly large, so copying may be an expensive operation.
