I need to double-check to make sure that none of the ports will conflict at a
low offset #. e.g.: shouldn't use 600+offset & 610+offset because it won't
support more than 10 servers then. I think I saw that conflict last night, but
just wanted to get some eyes/opinions on this.

This JIRA also needs an associated wiki article change. So, the workflow would
be:
./bin/start-hbase.sh
./bin/local-master-backup start 1
I don't think you would want to use this file to start the original master, use
start-hbase.sh for that. You primarily want to use this script to test master
failover conditions.

offset is not only the port offset, but also an identifier for the logs. The
log for "./bin/local-master-backup.sh start 1" would be located at
logs/hbase-<user>-1-master-<server>.log
In an internal review, Kannan asked why you couldn't use "start 0", I thought
offset would help explain that issue. opinions?

oops. probably cut+paste error. can correct

ooops. I had some stuff from HBASE-2312 sneak in. I'll correct that
