Vinayakumar B commented on HDFS-10440: -------------------------------------- I was thinking about incompatible change done in {{DataNodeMXBean#getNamenodeAddresses()}}. Patch returns more information than just addresses. Instead of breaking compatibility, how about adding one more metric entry, ex: {{getNameNodesInfo()}}, this way we would keep the compatibility also, i.e. Adding a new JMX entry is compatible mentioned [here|http://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/Compatibility.html#MetricsJMX]. Address information is redundant, but better than breaking compatibility.
