Hi all, I want to obtain counters of a task after it's completion to do some bookkeeping. I am using the JobTrackerInstrumentation class (a subclass actually) to get notifications about task completions. In the completeMap and completeReduce method of my class, I am obtaining the task counters as follows: --- // tid is TaskAttemptID, passed as an argument Counters taskCounters =tracker.getTaskStatus(tid).getCounters(); --- My question is, does the job tracker store status/counters of a particular task even after its completion? More specifically, how can I obtain counters of a task using just the TaskAttemptID?
