Hi [~anu]
Sure we can discuss each item in more detail. One comment to item 2 - Discovery
of Configs. This reminds me some work I've done in HADOOP-13628, it adds a
common rest API to retrieve configuration from a server. This was done in a
common {{ConfServlet}} which is enabled by default in HttpServer2. The work
done by Elek in HDFS-12007 should be able to get this covered so it won't be a
problem at all.
For 3 - Discovery of the root user. I am a bit confused. The auth check is
usually done in server side, which has access to configuration files. I am
curious why it is necessary to discover root users.
Thank you.

> Ozone: Ozone shell: the root is assumed to hdfs

>
> *hdfs oz* command, or ozone shell has a command like option to run some
> commands as root easily by specifying _--root_ as a command line option.
> But after HDFS-11655 that assumption is no longer true. We need to detect the
> user that started the scm/ksm service and _root_ should be mapped to that
> user.
