----------------------------------

             Summary: The digest of sub-plan reuse should contain RelNode's trait
                 Key: FLINK-15001
                 URL: https://issues.apache.org/jira/browse/FLINK-15001
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Planner
    Affects Versions: 1.9.1, 1.9.0
            Reporter: godfrey he
             Fix For: 1.10.0
         Attachments: image-2019-12-02-10-49-46-916.png, image-2019-12-02-10-52-01-399.png

This bug is found in [FLINK-14946| https://issues.apache.org/jira/browse/FLINK-14946]:

The plan for the given sql in [FLINK-14946| https://issues.apache.org/jira/browse/FLINK-14946] is
 !image-2019-12-02-10-49-46-916.png!

however, the plan after sub-plan reuse is:
 !image-2019-12-02-10-52-01-399.png!

in the first picture, we could find that the accMode of two joins are different, but the two joins are reused in the second picture.

The reason is the digest of sub-plan reuse does not contain RelNode's trait now.
