Review comment:
>> I dont see any point in logging a warning, since we can't
improve-upon/act-upon it
task.class is deprecated post 1.0. This log-warning is required to
communicate to users that they're using deprecated config in their job.
>> Task.subtask.class is not valid post samza 1.0.
No, it is just deprecated and it is not removed. Couple of high-end
jobs(incl atc, concourse) still use it after 1.0 release.
