I applied patch and built. On shutdown of a standalone instance I got this:
"pynchon-305:trunk stack$ ./bin/stop-hbase.sh
stopping hbase................../Users/stack/checkouts/trunk/bin/hbase-daemons.sh: line 49: /Users/stack/checkouts/trunk/bin/master-backup.sh: Permission denied
/Users/stack/checkouts/trunk/bin/hbase-daemons.sh: line 49: exec: /Users/stack/checkouts/trunk/bin/master-backup.sh: cannot execute: Unknown error: 0"
My script looks to have x perms:
pynchon-305:trunk stack$ ls -la bin/hbase-daemons.sh
-rwxr-xr-x 1 stack staff 1628 Aug 9 20:21 bin/hbase-daemons.sh
The passed 'args' are bad for standalone?
trunk/bin/master-backup.sh

I don't understand this construct Nicolas (My shell scripting requires me to have a book or a web page open while I write -- currently its not present).

> Adds '--backup' option to HMaster. All backup masters will wait until a primary master has written the /hbase/master znode before poll waiting. This allows us to have a deterministic primary master while starting up multiple masters. Note that you can specify a list of backup masters to automatically start/stop via the 'conf/backup-masters' file.
