[jira] [Created] (FLINK-20304) Fail hard when trying to run job with broadcast state in BATCH execution mode

Till Rohrmann created FLINK-20304:
-------------------------------------

             Summary: Fail hard when trying to run job with broadcast state in BATCH execution mode
                 Key: FLINK-20304
                 URL: https://issues.apache.org/jira/browse/FLINK-20304
             Project: Flink
          Issue Type: Bug
          Components: API / DataStream
    Affects Versions: 1.12.0
            Reporter: Till Rohrmann
             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.
