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

             Summary: Fix CombineHint documentation
                 Key: FLINK-7234
                 URL: https://issues.apache.org/jira/browse/FLINK-7234
             Project: Flink
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.2.2, 1.4.0, 1.3.2
            Reporter: Greg Hogan
            Assignee: Greg Hogan


The {{CombineHint}} [documentation|https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/batch/index.html] applies to {{DataSet#reduce}} not {{DataSet#reduceGroup}} and should also be note for {{DataSet#distinct}}. It is also set with {{.setCombineHint(CombineHint)}} rather than alongside the UDF parameter.
