> Project: Flink
> Issue Type: Bug
> Components: API / DataStream
> Affects Versions: 1.9.0, 1.9.1
> Reporter: Yun Gao
> Priority: Major
> Labels: pull-request-available
>
> StreamingJobGraphGenerator.isChainable dose not consider the coLocationGroup,
> if A -> B is chained, the coLocationGroup of the corresponding JobVertex will
> be set with that of the head node, namely A. Therefore, if B has declared
> coLocationGroup but A does not, then the coLocationGroup of B will be ignored.
