I identified the following issues:
- Setting the configuration using the yarn session "dynamic properties":
`./bin/yarn-session.sh -n 2 -Dfs.default-scheme=hdfs:///` does not really work
(the configuration parameter shows up in the web interface, but the job fails)
- Setting a false schema leads to a null pointer exception on job
submission. In the flink-conf.yaml, I have `fs.default-scheme: thisIsWrong`.
Look at this:
