Rajesh Balamohan created TEZ-4250:
-------------------------------------

             Summary: Optimise TaskImpl::getCounters 
                 Key: TEZ-4250
                 URL: https://issues.apache.org/jira/browse/TEZ-4250
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Rajesh Balamohan
         Attachments: image-2020-11-17-14-05-09-294.png

It would be good to have the temp counters only when speculation is enabled. Current impl causes overhead for short running queries/tasks.
