Subject [jira] [Updated] (HADOOP-15867) Allow registering MBeans without additional jmx properties
Date Sun, 21 Oct 2018 21:46:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15867?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
