-----------------------------------------
Hey [~jira.shegalov] or [~ozawa], would you mind taking a second look and
committing if you're okay with this?

> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6298
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Lars Francke
> Assignee: Lars Francke
> Priority: Minor

> 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.
