org.apache.zookeeper.server.quorum.flexible.QuorumHierarchical
This class implements a validator for hierarchical quorums. With this construction, zookeeper servers are split into disjoint groups, and each server has a weight. We obtain a quorum if we get more than half of the total weight of a group for a majority of groups. The configuration of quorums uses two parameters: group and weight. Groups are sets of ZooKeeper servers, and we set a group by passing a colon-separated list of server ids. It is also necessary to assign weights to server. Here is an example of a configuration that creates three groups and assigns a weight of 1 to each server: group.1=1:2:3 group.2=4:5:6 group.3=7:8:9 weight.1=1 weight.2=1 weight.3=1 weight.4=1 weight.5=1 weight.6=1 weight.7=1 weight.8=1 weight.9=1 Note that it is still necessary to define peers using the server keyword.
