      Description

      We collect execution metrics in each Executor's MetricManagerWorker and send it to MetricManagerMaster, which looks like the following:

       

      master.MetricManagerMaster: {"computationUnitId":"Stage-0-TaskGroup-409", "metricList":[
      {"EndTime":1523534503827,"ContainerId":"Master","StartTime":1523534457564,"ToState":"ON_HOLD","ElapsedTime(ms)":46263,"FromState":"EXECUTING"}, {"EndTime":1523534504085,"InputReadTime(ms)":18660,"StartTime":1523534457869,"ReadBytes":0,"ElapsedTime(ms)":46216,"BoundedSourceReadTime(ms)":27393}]}
      

       

      Currently, parts of TaskGroup execution metrics are lost occasionally. We need to fix this bug.
