Date Thu, 24 Oct 2019 11:21:00 GMT
Yun Gao created FLINK-14521:
-------------------------------

             Summary: CoLocationGroup is not set into JobVertex if the stream node chained
with others
                 Key: FLINK-14521
                 URL: https://issues.apache.org/jira/browse/FLINK-14521
             Project: Flink
          Issue Type: Bug
          Components: API / DataStream
    Affects Versions: 1.9.1, 1.9.0
            Reporter: Yun Gao


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.
