> Job#toString calls {{ensureState(JobState.RUNNING);}} as the very first thing. That method causes an Exception to be thrown which is not nice.
> One thing this breaks is usage of Job on the Scala (e.g. Spark) REPL as that calls toString after every invocation and that fails every time.
> I'll attach a patch that checks state and if it's RUNNING prints the original message and if not prints something else.
