If you're not ingesting to anything hosted by that tserver, doing a
flush of the tables with tablets on that tserver (that info should be
available on the monitor page), should avoid long log recoveries.
You should be able to shut down a single tablet server with
"bin/stop-here.sh" or "bin/accumulo admin $host" ($host, as it appears
in the slaves file).
