 says that GenericOptionsParser is the proper place to add options. Since the 
static configuration will get removed after sometime, is it required to be 
public now?
Till the time user apps are moved to implementing Tool, users could set the 
values for the options tmpfiles, tmparchives and tmpjars in the configuration 
they use to submit jobs (that's what the three arguments, -files, -archives and 
-jars, do).

Thoughts?

> -libjars options is available only if the job has been submitted through 
> JobShell class. Since the function 'setCommnadLineConfig' is a protected 
> function, non mapred classes can't take advantage of this functionality. By 
> making this function public, other classes that submit jobs can utilize this 
> functionality.
