Dennis Kubes updated HADOOP-2286:
---------------------------------
Attachment: HADOOP-2286-1-20071213.patch
Adds a shutdown hook to the regionserver to allow region servers to safely
shutdown through a kill signal. The hbase-daemon.sh script has been changed to
allow shutdown of region server on the local box through the command
"bin/hbase-daemon.sh stop regionserver"
> [hbase] Add being able to shutdown regionservers

>
> You can't shutdown regionservers from the commandline:
> durruti:~/Documents/checkouts/hadoop-trunk/src/contrib/hbase stack$
> ./bin/hbase regionserver stop
> There is no regionserver stop mechanism. To stop regionservers, shutdown the
> hbase master
> The above was done intentionally to scare folks toward shutting down clusters
> from the master.
> But, as Paul Saab points out, if a server is errant, you'll want to be able
> to shut it down gracefully.
> Enable individual regionserver shutdown from command line and optionally from
> the UI.
