Sequence of Streaming Jobs

[Dan Milstein]

If I've got a sequence of streaming jobs, each of which depends on the  
output of the previous one, is there a good way to launch that  
sequence?  Meaning, I want step B to only start once step A has  
finished.

From within Java JobClient code, I can do submitJob/runJob, but is  
there any sort of clean way to do this for a sequence of streaming jobs?

Thanks,
