Owen O'Malley commented on HADOOP-5785:
---------------------------------------
You should define a setter and getter for the variable. In particular, it
should go into the new Job and JobContext, respectively.
If the variable is set, no initialization or cleanup should be done. The
assumption is that the application needs no setup or cleanup or it will be
handled externally from something like Pig, Oozie, or Hive.
> The job setup and cleanup tasks should be optional
