> The behavior of mapred.cache.files and mapred.cache.archives is different during localization
in the following way:
> If a jar file is added to mapred.cache.files,  it will be localized under TaskTracker
under a unique path. 
> If a jar file is added to mapred.cache.archives, it will be localized under a unique
path in a directory named the jar file name, and will be unarchived under the same directory.
> If same jar file is passed for both the configurations, the behavior undefined. Thus
the job submission should fail.
> Currently, since distributed cache processes files before archives, the jar file will
be just localized and not unarchived.
