[hbase] Add being able to shutdown regionservers
------------------------------------------------
Key: HADOOP-2286
URL: https://issues.apache.org/jira/browse/HADOOP-2286
Project: Hadoop
Issue Type: Improvement
Reporter: stack
Priority: Minor
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.
