      Description

      Currently, in `ChiSqSelectorModel`, save:

      spark.createDataFrame(dataArray).repartition(1).write...
      

      The default partition number used by createDataFrame is "defaultParallelism",
      Current RoundRobinPartitioning won't guarantee the "repartition" generating the same order result with local array. We need fix it.
