-------------------------------------
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.
