> Project: HBase
> Issue Type: Improvement
> Components: regionserver, scan
> Reporter: Xuesen Liang
> Assignee: Xuesen Liang
> Priority: Minor
> Fix For: 2.5.0, 3.0.0-alpha-2

>
> 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.
