Agree. Let's commit this patch. I found one small problem, after that, I can
commit it.
I also added [~Huachao] to the HDDS project as a contributor. Now you can
assign issues to yourself.

[~elek], [~aengineer], thanks for the insights. I'm fine with either fixing or
removing it. Since the [fix is almost
ready|https://github.com/apache/hadoop-ozone/pull/105], I think it would be
nice to accept [~Huachao]'s contribution, and then create a follow-up task to
remove the feature completely. IMO if it's to be removed, it should be cut
from the code, too, not only from the doc.

Yeap, I am fine with removing it. I don't think we are testing or running the
plugin inside HDFS any more.

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.

Attila Doroszlai commented on HDDS-2370:
Thanks for reporting this problem [~Huachao]. I think datanode plugin behavior
should be fixed instead of removing it from the documentation. Would you like
to work on it, or may I?
