It was an early idea to make it easier to run Ozone as part of the HDFS.
Personally I don't think it's a realistic use case any more. I think It's
better to separate the JVMs and run two different type of datanodes.
Last time [~anu] suggested to keep it, but I am open to remove it, especially
as this path is usually un-tested.
[~anu] What do you think?
