Description

The message logged by the RegionServer when a Scanner lease expires isn't as useful as it could be. Scanner 4765412385779771089 lease expired - most clients don't log their scanner ID, so it's really hard to figure out what was going on. I think it would be useful to at least log the name of the region on which the Scanner was open, and it would be great to have the ip:port of the client that had that lease too.
