> StreamJob submit the job and use a while loop monitor the progress.
> I prefer it running on background.
> Just add "&" at the end of command is a alternative solution, but it keeps a
> java process on client machine.
> When submit hundreds jobs at the same time, the client machine is overloaded.
> Adding a -background option to StreamJob, tell it only submit and don't
> monitor the progress.
