Subject [jira] Created: (HADOOP-2208) Reduce frequency of Counter updates in the task tracker status

Reduce frequency of Counter updates in the task tracker status
--------------------------------------------------------------

                 Key: HADOOP-2208
                 URL: https://issues.apache.org/jira/browse/HADOOP-2208
             Project: Hadoop
          Issue Type: Improvement
            Reporter: Amareshwari Sri Ramadasu


Currently,  We have counter updates from task tracker to job tracker on every heartbeat. Both
counter name and the values are updated for every heartbeat. This can be improved by sending
names and values for the first time and only the values after that.
The frequency can be reduced by doing update only when the counters got changed.
