             Summary: Row type does not serialize in to readable format when invoke "toString" method
                 Key: FLINK-11569
                 URL: https://issues.apache.org/jira/browse/FLINK-11569
             Project: Flink
          Issue Type: Bug
          Components: Type Serialization System
            Reporter: Rong Rong
            Assignee: Rong Rong


Seems like the "toString" method for Row type is only concatenating all fields using COMMA ",". However it does not wrap the entire Row in some type of encapsulation, for example "()". This results in nested Row being serialized as if they are all in one level.

For example: {{Row.of("a", 1, Row.of("b", 2))}} is printed out as {{"a",1,"b",2}}.
