    Description

      The current directory structure for my test script is as follows:
      project/
      script/
      _init_.py
      map.py
      test/
      _init.py_
      test_map.py

      I have attached map.py and test_map.py file with this issue.

      When I run the nosetest in the test directory, the test fails. I get no module named "script" found error.
      However when I modify the map_add function to replace the call to add within reduceByKey in map.py like this:

      def map_add(df):
      result = df.map(lambda x: (x.key, x.value)).reduceByKey(lambda x,y: x+y)
      return result

      The test passes.

      Also, when I run the original test_map.py from the project directory, the test passes.

      I am not able to figure out why the test doesn't detect the script module when it is within the test directory.

      I have also attached the log error file. Any help will be much appreciated.
