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. -- This is an automated message from the Apache Git Service.
