code: def addFile(self, path, recursive=False):
          
          self._jsc.sc().addFile(path, recursive)
docs: Add a file to be downloaded with this Spark job on every node.
          The C{path} passed can be either a local file, a file in HDFS
          (or other Hadoop-supported filesystems), or an HTTP, HTTPS or
          FTP URI.
  
          To access the file in Spark jobs, use
          L{SparkFiles.get(fileName)<pyspark.files.SparkFiles.get>} with the
          filename to find its download location.
  
          A directory can be given if the recursive option is set to True.
          Currently directories are only supported for Hadoop-supported filesystems.
  
          .. note:: A path can be added only once. Subsequent additions of the same path are ignored.
  
          >>> from pyspark import SparkFiles

          >>> with open(path, "w") as testFile:
          ...    _ = testFile.write("100")
          >>> sc.addFile(path)
          >>> def func(iterator):
          ...    with open(SparkFiles.get("test.txt")) as testFile:
          ...        fileVal = int(testFile.readline())
          ...        return [x * fileVal for x in iterator]
          >>> sc.parallelize([1, 2, 3, 4]).mapPartitions(func).collect()
