Review comment:
Why do you remove `50470` here? Is it because we switch to random ports
for the namenode's HTTPS port? If yes: Why don't we also remove `50070` as
well? It's the namenode's HTTP port which also became random
([source](https://ambari.apache.org/1.2.3/installing-hadoop-using-ambari/content/reference_chap2_1.html)).
