Subject [jira] Commented: (HADOOP-2086) ability to add dependencies to a job after construction
Date Fri, 26 Oct 2007 10:06:52 GMT

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.
