> HDDS and Ozone use the MBeans.register overload added by HADOOP-15339. This
> is missing in Apache Hadoop 3.1.0 and earlier. This prevents us from building
> Ozone with earlier versions of Hadoop. More commonly, we see runtime
> exceptions if an earlier version of the Hadoop-common jar happens to be in
> the classpath.
> Let's add a reflection-based switch to invoke the right version of the API so
> we can build and use Ozone with Apache Hadoop 3.1.0.
