> With a few thousands issues ago Ozone was integral part of Hadoop/HDFS project. At that time there were two options to start datanode:
> 1. Start in a separated JVM
> 2. Start in the same JVM with the HDFS
> Today only 1 is the standard way, this is tested and working. 2nd is not working any more but still documented.
> I propose to drop the support of this use case as I can't see any benefit to support it anymore:
> 1. I think 100% of the users will use Ozone as a separated process not as a HDFS Datanode plugin
> 2. Fixing the classpath issues is significant effort as the classpath of HDFS and Ozone are diverged.
