    Description

      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().
