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

             Summary: Move DataStreamUtils to package 'experimental'.
                 Key: FLINK-8837
                 URL: https://issues.apache.org/jira/browse/FLINK-8837
             Project: Flink
          Issue Type: Bug
          Components: Streaming
            Reporter: Stephan Ewen
             Fix For: 1.5.0


The class {{DataStreamUtils}} came from 'flink-contrib' and now accidentally moved to the fully supported API packages. It should be in package 'experimental' to properly communicate that it is not guaranteed to be API stable.
