Arun C Murthy commented on HADOOP-1622:
---------------------------------------

Dennis, I'm sorry to come in late on this... a couple of comments:

1. Could you please remove the mention of 'final' and 'default' config 
resources from the javadoc for {{JobConf.{get|set}JobResources}}? They are no 
longer relevant vis-a-vis hadoop Configuration.
2. Should we also have a {{JobConf.setJobResource}} along with 
{{JobConf.addJobResource}}, ala {{DistributedCache} apis?
3. Should we move the private {{JobClient.createJobJar}} method to JarUtils to 
make it available as a useful utility?

Unrelated: Does it make sense to rename {{Configuration.addResource}} to 
{{Configuration.addConfigResource}}? I wonder how confusing these unrelated api 
names are, given {{JobConf}} _is a_ {{Configuration}} too ...

> 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
