Vinod K V commented on HADOOP-5785:
-----------------------------------
bq.If not a method, it can be a simple protected boolean
OutputCommitter.isJobSetupNeeded over-ridable by subclasses. Does that work?
I take that back. Even reading this variable on the JobTracker needs the class
to be loaded which in turn means running user code.
So, +1 for the initial proposal for a configuration property. +1 for job-level
configuration.
> The job setup and cleanup tasks should be optional
