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?---
