Python Hadoop Streaming Error “ERROR streaming.Str

I am trying to run python script on Hadoop cluster using Hadoop Streaming for sentiment analysis. The Same script I am running on Local machine which is running Properly and giving output.
to run on local machine I use this command.

$ cat /home/MB/analytics/Data/input/* | ./new_mapper.py

and to run on hadoop cluster I use below command

$ hadoop jar /usr/lib/hadoop-0.20-mapreduce/contrib/streaming/hadoop-streaming-2.5.0-mr1-cdh5.2.0.jar -mapper "python $PWD/new_mapper.py" -reducer "$PWD/new_reducer.py" -input /user/hduser/Test_04012015_Data/input/* -output /user/hduser/python-mr/out-mr-out

The Sample code of my script is

#!/usr/bin/env python
import sys


def main(argv):
##    for line in sys.stdin:
##        print line
    for line in sys.stdin:
        line = line.split(',')
        t_text      = re.sub(r'[?|$|.|!|,|!|?|;]',r'',line[7])
        words    = re.findall(r"[\w']+", t_text.rstrip())
        predicted = classifier.classify(feature_select(words))
        i=i+1
        referenceSets[predicted].add(i)
        testSets[predicted].add(i)
        print line[7] +'\t'+predicted

if __name__ == "__main__":
    main(sys.argv)

The stack trace of Exception is:

I tried to see logs but in hue it shows me this error. Please suggest me, what is going wrong.

It looks like you forgot to add the file new_mapper.py to your job.

Basically, your job tries to run the python script new_mapper.py, but this script is missing on the server running your mapper.

You must add this file to your job, using the option -file <local_path_to_your_file>.
