Easily supports the Join. To use the setSimpleJoin,
you must be a size master data appear in the memory of the task.
@param masterLabels label of master data
@param masterColumns master column's
@param dataColumns data column's
@param masterPath master data HDFS path
@return this
@throws DataFormatException
