Bill Graham commented on PIG-2664:
----------------------------------
There's also EmbeddedPigStats which is used when Pig is running in embedded
mode. It also subclasses PigStats but throws UnsupportedOperationException
exceptions for most of the abstract methods it implements. We can follow the
same approach with an abstract getJobClient() method.
I also don't love the ((SimplePigStats)PigStats.get()).getFoo() approach, but
it's the pattern already in use in PigStatsUtil and other options didn't seem
great. I'm ok with moving getJobClient it to PigStats though. That way we can
at least get rid of the cast.

>
> Implementations of PigProcessNotificationListener don't have access to much
> job-related into until after the job is completed. A few minor edits to
> PigStatsUtil can change that.
> - Expose the JobClient
> - Set an initial JobStats object upon kicking off a job. This makes JobId
> available to clients once it's assigned.
