Map reduce on multiple clusters

[sorna lingam]

Hi all

Im having two clusters [windows]  DEV140 and DEV144 . Where DEV144 is master and DEV140 is slave 

And im having Map/ Reduce program which is written in python - in DEV144[master] local disk [C:\Python33\..]

using the following code i run the mapreduce 

hadoop  jar /HDP/hadoop-1.2.0.1.3.0.0-0380/contrib/streaming/hadoop-streaming-1.2.0.1.3.0.0-0380.jar  -mapper "python C:\Python33\mapper.py"  -reducer "python C:\Python33\redu.py"  -input "/user/sornalingam/input/input.txt"  -output "/user/sornalingam/output/out20131113_15"  

And In DEV144  every job got success but in DEV140 i got this error in the log file 

stderr logs

python: can't open file 'C:\Python33\mapper.py': [Errno 2] No such file or directory
java.lang.RuntimeException: PipeMapRed.waitOutputThreads(): subprocess failed with code 2
	at org.apache.hadoop.streaming.PipeMapRed.waitOutputThreads(PipeMapRed.java:362)

Now 

1. Do i need to copy my Map/Reduce prog in all the cluster ?

2. How can i solve this problem 

Kindly help me 

Im newbie to hadoop 

Thanks
