Github user StephanEwen commented on the issue: https://github.com/apache/flink/pull/6118 I think this is a misdiagnosis, this should not be merged. Flink does not need a file system factory for Hadoop, it uses Hadoop's FS as the general fallback for all schemes that it does not have a factory for. The exception in the linked JIRA comes from Hadoop's own File System discovery. There is probably some casting error or so (may be due to inverted classloading).
