GenericOptionsParser is customized only for Hadoop specific params :
* <code>GenericOptionsParser</code> recognizes several standarad command
* line arguments, enabling applications to easily specify a namenode, a
* jobtracker, additional configuration resources etc.
Ideally, all params must be passed via Tool interface. In my application, I have a custom serialiizer/deseralizer classes to parse any xml file I might be supplying, which I use to generate some metadata. This can be a part of the above interface as well. Hope this helps.

Subject: passing job arguments as an xml file
I am looking at an easy way to passing the job arguments trough a config file.
The genericoptionsparser seems to parse only the hadoop options.
Normally i use jsap but that would not co-exist with genericoptionsparser ....
