---------------------------------------

             Summary: NPE when getting metrics of backup master
                 Key: HBASE-25480
                 URL: https://issues.apache.org/jira/browse/HBASE-25480
             Project: HBase
          Issue Type: Brainstorming
          Components: master
    Affects Versions: 2.4.0
            Reporter: Andrey Elenskiy


Getting NullPointerException in MetricsMasterWrapperImpl.getMergePlanCount() when getting metrics via JMX on backup master. It appears due to the fact that regionNormalizerManager is null in backup masters as it's only initialized by HMaster.finishActiveMasterInitialization().
