-------------------------------
Description:
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 retraction traits
for stream physical nodes now.
