>          Components: contrib/streaming
>    Affects Versions: 0.17.0
>            Reporter: Suhas Gogate

>
> Hadoop 0.17 streaming allows specifying multiple user specific jar files on the command line along with the hadoop-streaming.jar. These user specific jar files are not automatically  added on the client side class path when hadoop runs the streaming job
> For example, in the following streaming job <user-app.jar> is not automatically included in client side path before executing the streaming job
>  
> hadoop  jar -libjars <user-app.jar> $HADOOP_HOME/hadoop-streaming.jar \
>         -input </input-data-path> \
>         -output </output data path> \
>         -inputformat  <Input-format> \
>         -outputformat <OutputFormat> \
>         -mapper /bin/cat -reducer /bin/cat \
>         -additionalconfspec  <xxxx> \
>         -jobconf mapred.reduce.tasks=3\
> Workaround:
> Current work around is to set these user specific jar files in
> HADOOP_CLASSPATH environment variable on the client side before running above example.
