> With hadoop-0.20.0 proper error message is not thrown , when streaming job is submitted and if file is not present to be distributed with "-file" option. But with hadoop-0.18.* proper verbose message is thrown if file is not present and it is easy for the users to debug.
> For example:
> With hadoop-0.20.0:
> $ hadoop jar $HADOOP_HOME/hadoop-streaming.jar -Dmapred.job.queue.name=general -input /user/simon/test1.txt -output /user/simon/test.out -mapper "/bin/cat" -file dummy -reducer "/bin/cat"
> Streaming Job Failed!
> With hadoop-0.18.*:
> $ hadoop jar $HADOOP_HOME/hadoop-streaming.jar -input /user/simon/test1.txt -output /user/simon/test.out -mapper "/bin/cat" -file dummy -reducer "/bin/cat"
> 09/10/06 10:06:49 ERROR streaming.StreamJob: Unexpected value "Argument : /home/simon/dummy doesn't exist." found while processing -file
