> 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.
