Examples of ZooKeeperInstance

io.fathom.auto.zookeeper.ZookeeperInstance
org.apache.accumulo.core.client.ZooKeeperInstance

An implementation of instance that looks in zookeeper to find information needed to connect to an instance of accumulo.
The advantage of using zookeeper to obtain information about accumulo is that zookeeper is highly available, very responsive, and supports caching.
Because it is possible for multiple instances of accumulo to share a single set of zookeeper servers, all constructors require an accumulo instance name. If you do not know the instance names then run accumulo org.apache.accumulo.server.util.ListInstances on an accumulo server.
