I've run HBase from version 0.90.2 to our current 0.94.6 (CDH 4.3) and have never specified a --backup option on any of my commands with regard to the master. You're correct that they race to be active, and failover is completely automatic in the case of one master going down.
TBH I've never even heard of a --backup argument, so I'm wondering if it is something extremely old or extremely new :) On Mon, Dec 9, 2013 at 6:24 AM, Manuel de Ferran <[email protected]>wrote: > Greetings, > > I'm playing without MultiMaster, and I was wondering if --backup is really > needed. > > As far as I have observed, masters race to be the active one.
