-------------------------------------

             Summary: 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


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?
