>
> 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.
