'conf/backup-masters' are not meant to be local instances, just like extra
regionservers aren't. Hence bin/local-master-backup.sh &
bin/local-regionserver.sh (trying to stay consistent). However, I didn't
originally test this in local mode, only a cluster. Tested in local mode and
got the same error. I ran 'chmod +x bin/master-backup.sh' and the problem went
away. Let me know if you still have problems. Should run fine other than
that.
I did notice that I need to place 'stop master-backup' inside the distributed
conditional. Will fix on the next update.

this performs string substitution on ${args} and changes 'master-backup' to
'master'. The remote command to call is 'hbase-daemon.sh start master
--backup'. I'm changing to ${args/master-backup/master} for a little more
clarity
