Hi community, Recently we found out an issue with the Top-N feature in blink planner, and here is the JIRA ticket https://issues.apache.org/jira/browse/FLINK-18452.
After analysis, we believe that it is the flaw in the implementation of equals method, as it does not take the random numbers within class names and variables into account during comparison. We would like to confirm whether this is actually an issue (mostly like one, as it is 100% reproducible using standard SQL APIs). Sincerely, Weike
