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

             Summary: Invalid check of key and ordering fields in PartitionNode
                 Key: FLINK-3935
                 URL: https://issues.apache.org/jira/browse/FLINK-3935
             Project: Flink
          Issue Type: Bug
          Components: Optimizer
    Affects Versions: 1.1.0
            Reporter: Fabian Hueske
            Assignee: Fabian Hueske
             Fix For: 1.1.0


{{PartitionNode}} checks for range partitioning that partition keys and the fields of the
ordering are identical. However the check is not correctly implemented because {{PartitionNode}}
holds the partition keys as an unordered {{FieldSet}} which is compared against an ordered
{{FieldList}} provided by the {{Ordering}}.
