[jira] [Created] (FLINK-4736) Don't duplicate fields in Ordering

Greg Hogan created FLINK-4736:
---------------------------------

             Summary: Don't duplicate fields in Ordering
                 Key: FLINK-4736
                 URL: https://issues.apache.org/jira/browse/FLINK-4736
             Project: Flink
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.2.0
            Reporter: Greg Hogan
            Assignee: Greg Hogan
            Priority: Minor
             Fix For: 1.2.0


Duplicate fields should not be appended to an ordering. In an ordering each subsequent field is only used as a comparison when all prior fields test equal; therefore, a repeated field cannot contribute to the ordering.
