Arpit Agarwal updated HADOOP-15867:
-----------------------------------
Description:
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.
