[jira] Updated: (HBASE-2871) Make "start|stop" commands symmetric for Master & Cluster

Nicolas Spiegelberg updated HBASE-2871:
---------------------------------------

    Attachment: HBASE-2871.patch

Patch changes "stop master" to actually just stop the master and stop-hbase.sh should be the only "quick command" to stop the cluster.  Note that you can run bin/stop-hbase.sh on a unit that is not the master.  If not on the HMaster server, the script will not wait for the HMaster to stop before proceeding but should properly shutdown the system.

> Currently, our master & server start/stop commands aren't asymmetric.  Calling "hbase-daemon.sh start master" will create a single Master process, but calling "hbase-daemon.sh stop master" will stop the master + regionservers.  Additionally, running bin/stop-hbase.sh will not work properly if a backup master is currently the primary.  We should modify these commands so they are intuitive/asymmetric and let the HBase contributors (instead of users) live with the fact that it might be a little ugly underneath.
