Github user StephanEwen commented on the issue: https://github.com/apache/flink/pull/6118 Where in the loading of the factories do you see the error? My suspicion is still an issue with inverted class loading. To confirm, can we check the following? - Are you running this on Flink 1.4.0 or 1.4.1? - Do you have `hadoop-common` in the job's jar, or in the `flink/lib` folder? - Does the error go away if you set "classloader.resolve-order: parent-first" in the config?
