Multi-master info missing from book?

Hi,

I was looking for info about running multiple HBase masters on
http://hbase.apache.org/book.html and wasn't able to find any
references to it.  I think I spotted one mention of "active" in the
context of master, but nothing else.

Either I'm not seeing it there, or I'm not looking at the right place,
or the info about this is lacking?

Thanks,
Otis

Yes. Just start HMaster on 2 different servers and they will fight it out

Regards,

Thanks Ted.  That's good, but shouldn't there be some info about how
to run multiple masters?  Is it as simple as starting hmaster on 2
different servers and have them fight it out?

I found:

2.5.1.2. If a backup Master, making primary Master fail fast
