             Summary: Micro optimization - Remove duplicate updateProcessTree() in TaskCounterUpdater
                 Key: TEZ-1090
                 URL: https://issues.apache.org/jira/browse/TEZ-1090
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Rajesh Balamohan
            Assignee: Rajesh Balamohan
             Fix For: 0.5.0


In TaskCounterUpdater, updateProcessTree() is invoked from initResourceCalculatorPlugin & recordInitialCpuStats.  With ResourceCalculatorProcessTree, close to 300-500 ms is wasted in every task launch.
