      Description

      Noticed incorrect value in ExpiredHeartbeats metrics under namenode JMX.

      We will increment ExpiredHeartbeats count when Datanode is dead but somehow we missed to decrement when datanode is alive back.

      
      { "name" : "Hadoop:service=NameNode,name=FSNamesystem", "modelerType" : "FSNamesystem", "tag.Context" : "dfs", "tag.TotalSyncTimes" : "7 ", "tag.HAState" : "active", ... "ExpiredHeartbeats" : 2, ... }
