> In {{AsyncProcess.SingleServerRequestRunnable}}, it seems we update
> serverStatistics twice.
> The first one is that we wrapper {{RetryingCallable}} by
> {{StatsTrackingRpcRetryingCaller}}, and do serverStatistics update when we
> call {{callWithRetries}} and {{callWithoutRetries}}. Relates code like below:
> {code}
> @Override
> public T callWithRetries(RetryingCallable<T> callable, int callTimeout)
> throws IOException, RuntimeException {
> T result = delegate.callWithRetries(callable, callTimeout);
> return updateStatsAndUnwrap(result, callable);
> }
> @Override
> public T callWithoutRetries(RetryingCallable<T> callable, int callTimeout)
> throws IOException, RuntimeException {
> T result = delegate.callWithRetries(callable, callTimeout);
> return updateStatsAndUnwrap(result, callable);
> }
> {code}
> The secondary one is after we get response, in {{receiveMultiAction}}, we do
> update again.
> {code}
> // update the stats about the region, if its a user table. We don't want to
> slow down
> // updates to meta tables, especially from internal updates (master, etc).
> if (AsyncProcess.this.connection.getStatisticsTracker() != null) {
> result = ResultStatsUtil.updateStats(result,
> AsyncProcess.this.connection.getStatisticsTracker(), server, regionName);
> }
> {code}
> It seems that {{StatsTrackingRpcRetryingCaller}} is NOT necessary, remove it?
