> Many split related metrics were present RS side but after split is moved to
> Master, these metrics are lost.
> 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,
