----------------------------------------
[~aljoscha] can you take a look and potentially adjust the priority of this
ticket (Only if you make it a blocker, it'll be considered for delaying the
next RC)
> Fail hard when trying to run job with broadcast state in BATCH execution mode

> URL: https://issues.apache.org/jira/browse/FLINK-20304
> Project: Flink

> Reporter: Till Rohrmann
> Priority: Critical
> Fix For: 1.12.0

>
> Contrary to the documentation it is currently possible to run a job with
> broadcast state in {{BATCH}} execution mode. Since accessing the keyed state
> from the broadcast side fails, we shouldn't allow the submissions of these
> kind of jobs in the first place. Hence, I would suggest to fail hard if one
> tries to run a job using the broadcast state pattern in {{BATCH}} execution
> mode.
