## Class DataPartitionerRemoteSparkMapper

- java.lang.Object
- - org.apache.sysds.runtime.controlprogram.parfor.ParWorker
  - - org.apache.sysds.runtime.controlprogram.parfor.DataPartitionerRemoteSparkMapper

- All Implemented Interfaces:
    Serializable, org.apache.spark.api.java.function.PairFlatMapFunction<scala.Tuple2<MatrixIndexes,MatrixBlock>,Long,org.apache.hadoop.io.Writable>

      public class DataPartitionerRemoteSparkMapper
      extends ParWorker
      implements org.apache.spark.api.java.function.PairFlatMapFunction<scala.Tuple2<MatrixIndexes,MatrixBlock>,Long,org.apache.hadoop.io.Writable>

  NOTE: for the moment we only support binary block here TODO extend impl for binarycell and textcell Interface of Writable output in order to support both PairWritableBlock and PairWritableCell.
