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

             Summary: Some generated functions are not opened properly.
                 Key: FLINK-10770
                 URL: https://issues.apache.org/jira/browse/FLINK-10770
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
    Affects Versions: 1.6.2, 1.7.0
            Reporter: wangsan


Recently I found sometimes UDFs are not open properly. It turns out when transforming sql to execution plan, some generated functions' *open* method are not called. e.g. *NonWindowJoin*, *TimeBoundedStreamJoin*, *FlatJoinRunner*.
