------------------------------------

This would be much more useful if you could do a jstack as Pavan suggested.

> After executing ConnectedComponentsVertex job memory is not deallocated. As system monitor shows, java processes that are created for this job are not killed and they are live until hadoop is stopped. It is not dependent to the job, this scenario is occurred for SimpleShortestPathsVertex job, too.
