Adrian Woodhead commented on HADOOP-2086:
-----------------------------------------

OK, I agree with all your comments. One final question and I'll submit another 
patch - is the READY state also acceptable for adding a depending job? Or is 
only WAITING valid?

> ability to add dependencies to a job after construction

> The current Job API only allows for dependent jobs to be passed in at object 
> construction time. It would be nice if there was an additional constructor 
> which did not take any depending jobs and then an "addDependingJob" method 
> which could be used to add depending jobs to a job at a later point.
