Subject Re: Accumulo rolling restart

And here's the command to do it:

$ bin/accumulo admin stop server[:port]


But recovery is pretty fast... killing tservers can be faster than doing an
orderly shutdown.

With 1.4, if I was restarting nodes on several racks, I would kill the
loggers on a rack, flush all tables, and then restart all the tservers and
loggers on that rack.  Rinse and repeat.
