We fixed the problem, but we are now running into actual test failures related to WebHdfs in case external-unstable is used:
logger.go:42: 09:05:06 | smoke_hadoop-3.3.4_zookeeper-3.8.3_zookeeper-latest-3.8.3_number-of-datanodes-2_datanode-pvcs-2hdd-1ssd_listener-class-external-unstable/50-create-file | requests.exceptions.ConnectionError: HTTPConnectionPool(host='hdfs-datanode-default-0.hdfs-datanode-default.kuttl-test-exciting-sloth.svc.cluster.local', port=32626): Max retries exceeded with url: /webhdfs/v1/testdata.txt?op=CREATE&user.name=stackable&namenoderpcaddress=hdfs&createflag=&createparent=true&overwrite=false (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fbe5b054a50>: Failed to establish a new connection: [Errno 111] Connection refused'))

This is probably caused because the POST to the NameNode redirects to a wrong DataNode address in the tests
