> The properties for hdfs-site/dfs.hosts and hdfs-site/dfs.hosts.exclude are generated on install (and config change). When creating a datanode post-install, the files get updated, but requires a restart of the NN in order to for it to read the new entry. In a normal install, DN should be able to register themselves without any restart.
