> This feature is new in Champlain.  
> This feature is intended for use in secure (Kerberized) clusters.  The full steps for configuration are:
> # Configure in hdfs-site.xml:
> ## Set {{dfs.data.transfer.protection}} to {{authentication}}, {{integrity}}, or {{privacy}}.  I think {{authentication}} makes sense as the default on new installs.
> ## Set {{dfs.datanode.address}} to use a non-privileged port, i.e. {{0.0.0.0:50010}}.
> ## Set {{dfs.datanode.https.address}} to use a non-privileged port, i.e. {{0.0.0.0:50475}}.
> ## Set {{dfs.http.policy}} to {{HTTPS_ONLY}}.
> # Start DataNode as hdfs.
> BTW, running as root using privileged ports is still a fully supported configuration.  This should continue to be the default mode.  Running as non-root is opt-in only, so all of the above should be optional.
