> Tracing is very important in large-scale distributed systems.
> The attribute *__operation.attributes.id_* of a scan request can be used as
> trace id between hbase client and region server.
> We should print operation id in region server's log if the scan request is
> too slow or too big.
> It will be very helpful for finding problematic requests.
