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

Sorry, another question upon looking at the code more: I see submit() also changes the state of the job, could this be another point for a race condition?

> 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.
