> More likely than not, a user's job may depend on multiple jars.
> Right now, when submitting a job through bin/hadoop, there is no way for the user to
specify that. 
> A walk around for that is to re-package all the dependent jars into a new jar or put
the dependent jar files in the lib dir of the new jar.
> This walk around causes unnecessary inconvenience to the user. Furthermore, if the user
does not own the main function 
> (like the case when the user uses Aggregate, or datajoin, streaming), the user has to
re-package those system jar files too.
> It is much desired that hadoop provides a clean and simple way for the user to specify
a list of dependent jar files at the time 
> of job submission. Someting like:
> bin/hadoop .... --depending_jars j1.jar:j2.jar
