[jira] [Commented] (HBASE-25542) Add client detail to scan name so when lease expires, we have clue on who was scanning

["Duo Zhang (Jira)" <ji...@apache.org>]

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?

> 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?
