             Summary: CoGroupedStreams$TaggedUnion cannot be used as a POJO type
                 Key: FLINK-27173
                 URL: https://issues.apache.org/jira/browse/FLINK-27173
             Project: Flink
          Issue Type: Bug
          Components: API / Type Serialization System
    Affects Versions: 1.14.4
            Reporter: Jun Qin
         Attachments: StreamingJob.java

Attached is the code to demo the issue.  When running the job, we can see the following:
{code:java}
11:48:26,584 INFO  org.apache.flink.api.java.typeutils.TypeExtractor            [] - class org.apache.flink.streaming.api.datastream.CoGroupedStreams$TaggedUnion does not contain a setter for field one
11:48:26,586 INFO  org.apache.flink.api.java.typeutils.TypeExtractor            [] - Class class org.apache.flink.streaming.api.datastream.CoGroupedStreams$TaggedUnion cannot be used as a POJO type because not all fields are valid POJO fields, and must be processed as GenericType. Please read the Flink documentation on "Data Types & Serialization" for details of the effect on performance. {code}
TaggedUnion is a class in Flink. This should be fixed in Flink.
