Umesh Kumar Kumawat updated HBASE-23996:
----------------------------------------
Description:
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, "splitProcedureTime_99th_percentile":
0, "splitProcedureTime_99.9th_percentile": 0 }
