Description

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.
