------------------------------------
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}}.
