      Description

      Many of the split related metrics like following are present RS side :

      "SplitTime_num_ops": 0,
      "SplitTime_min": 0,
      "SplitTime_max": 0,
      "SplitTime_mean": 0,
      "SplitTime_25th_percentile": 0,
      "SplitTime_median": 0,
      "SplitTime_75th_percentile": 0,
      "SplitTime_90th_percentile": 0,
      "SplitTime_95th_percentile": 0,
      "SplitTime_98th_percentile": 0,
      "SplitTime_99th_percentile": 0,
      "SplitTime_99.9th_percentile": 0,

      Value of these will always be 0 since Split is happening Master side and there is no Metrics update. 

       

       

      Update 1: After the fix, JMX is like this :

      { "name": "Hadoop:service=HBase,name=Master,sub=Procedure", "modelerType": "Master,sub=Procedure", "tag.Context": "master", "tag.Hostname": "blrphispra01257", "numMasterWALs": 0, "splitProcedure_RequestCount": 0, "splitProcedure_FailedCount": 0, "splitProcedure_SuccessCount": 0, "splitProcedureTime_num_ops": 0, "splitProcedureTime_min": 0, "splitProcedureTime_max": 0, "splitProcedureTime_mean": 0, "splitProcedureTime_25th_percentile": 0, "splitProcedureTime_median": 0, "splitProcedureTime_75th_percentile": 0, "splitProcedureTime_90th_percentile": 0, "splitProcedureTime_95th_percentile": 0, "splitProcedureTime_98th_percentile": 0, "splitProcedureTime_99th_percentile": 0, "splitProcedureTime_99.9th_percentile": 0 }
