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

             Summary: Consider changing the RichFunction#open method signature to take no arguments.
                 Key: FLINK-6912
                 URL: https://issues.apache.org/jira/browse/FLINK-6912
             Project: Flink
          Issue Type: Sub-task
          Components: DataSet API, DataStream API
    Affects Versions: 1.3.0
            Reporter: Mikhail Pryakhin
            Priority: Minor


RichFunction#open(org.apache.flink.configuration.Configuration) method takes a Configuration instance as an argument which is always [passed as a new instance|https://github.com/apache/flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/operators/AbstractUdfStreamOperator.java#L111] bearing no configuration parameters. As I figured out it is a remnant of the past since that method signature originates from the Record API. Consider changing the RichFunction#open method signature to take no arguments as well as actualizing java docs.
