Also, what do you mean by " don't know much about this particular job", does the type of the job jar file matter? I thought as long as I could locate the org.apache.mahout.utils.vectors.lucene.Driver class then I was good to use that job jar file.
Btw, whenever I installed and compiled mahout 0.7 (both from sorce and trunk), I couldnot locate the mahout-utils-0.7 jar. Why is this so?

There is likely some mechanism to package up arguments that need to be sent to the program, as an argument to the elastic-mapreduce binary.
