> I have an OutputFormat which implements Configurable. I set new config
> entries to a job configuration during checkOutputSpec() so that the tasks
> will get the config entries through the job configuration. This works fine
> in 0.20.2, but stopped working starting from 0.20.203. With 0.20.203, my
> OutputFormat still has the configuration set, but the copy a task gets does
> not have the new entries that are set as part of checkOutputSpec().
> I believe that the problem is with JobClient. The job configuration needs to
> wait till checkOutputSpec() is returned before being cloned and submitted.
