public final class HQuorumPeer
extends Object

HBase's version of ZooKeeper's QuorumPeer. When HBase is set to manage ZooKeeper, this class is used to start up QuorumPeer instances. By doing things in here rather than directly calling to ZooKeeper, we have more control over the process. This class uses ZKConfig to get settings from the hbase-site.xml file.
