>The RollingFileSink error might be due to
https://issues.apache.org/jira/browse/HDFS-9213. The secure MiniDFS cluster
requires privileged ports to be used and we need to enable the java process to
grant access if it is not running as root.
If we have to use privileged ports then we won't be able to use our CI
system. Are you sure it can only run in privileged mode? Is it not possible to
change the port binding to port >= 1024?
If you have previously ran `mvn install -DskipTests`, then you can use the
following to run the test:
```
mvn test integration-test -Dtest="YARNSessionFIFOSecuredITCase"
-Pinclude-yarn-tests -pl flink-yarn-tests
```
