Possible issue with pi estimation example

[ahutterTA]

When running the pi estimation example in KIND the Job succeeds and correctly reports the value of pi but all of the workers finish with a status of Error with nothing in their logs. Looking at https://github.com/uber/fiber/blob/master/fiber/process.py#L297 it appears that it's possible to have an exit code of 1 but without err being set. Is this intentional?

@ahutterTA I have same issue here. And seems like poolworker pods can only be triggered when create Job in 'default' namespace ?
