> 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.
