I am following a tutorial & executing a Amazon EMR ( Elastic MapReduce )

The error which I am receiving is:

Not a valid JAR: /home/hadoop/contrib/streaming/hadoop-streaming.jar

The steps that i took are after entering the credentials in putty

1) mkdir streamingCode`

2) wget -o ./streamingCode/wordSplitter.py s3://elasticmapreduce/samples/wordcount/wordSplitter.py

3) hadoop jar contrib/streaming/hadoop-streaming.jar -files streamingCode/wordSplitter.py -mapper wordSplitter.py input s3://elasticmapreduce/samples/wordcount/input -output streamingCode/wordCountOut -reducer aggregate`

While executing step 4 I am getting the error.
