Restarting a Region Server

Hi,
   I just bounced a region server. How do I start just this one region server and make sure it rejoins the cluster?

Thanks

On the host that is carrying the regionserver do:

  ./bin/hbase-daemon.sh stop regionserver

Then start it again.

Or, since 0.90.2, see bin/graceful_stop.sh.  It will let you do a
gradual decommission optionally restarting the regionserver after the
regions have been gently offloaded and then optionally again after the
server comes back, moving its old region burden back on to the
regionserver to preserve locality.  See
http://hbase.apache.org/book.html#decommission for more.
