as i know that HBase runs with ZooKeeper, it has 2 HMaster is active and inactive, So can i config many HMaster? Just like Hadoop have many namenode, can HBase have many HMaster? Thanks

HBase can have Backup Masters. Only one Master will be active at any time, but if it fails, one of the Backup Masters will become Master.

You specify Backup Masters in the /HBase/conf/backup-masters file Just list host name entries one per line, like you do for Region Servers.
