Duo Zhang commented on HBASE-25542:
-----------------------------------
I think when logging this line, we have a RegionScannerHolder at region server
side? Just record the client name in the RegionScannerHolder and log it out?
> Add client detail to scan name so when lease expires, we have clue on who was
> scanning

> Key: HBASE-25542
> URL: https://issues.apache.org/jira/browse/HBASE-25542
> Project: HBase
> Issue Type: Improvement
> Components: scan
> Affects Versions: 2.3.2
> Reporter: Michael Stack
> Priority: Major
>
> On a busy cluster, seeing a bunch of this:
> {code}
> regionserver.RSRpcServices: Scanner -5594731657924732088 lease expired on
> region hbase:meta,,1.1588230740
> {code}
> Trying to figure out originator is a little tough; there isn't enough in for
> in the above.
> scanid is a long but scan name is a string.. perhaps add in the client
> ip+port as scan id prefix? Or add the info to the value -- probably better --
> and dump it out when we get one of these expirations?
