org.apache.bookkeeper.zookeeper

Class BkZooKeeperClient

java.lang.Object

org.apache.zookeeper.ZooKeeper

org.apache.bookkeeper.zookeeper.BkZooKeeperClient

All Implemented Interfaces:

org.apache.zookeeper.Watcher

public class BkZooKeeperClient
extends org.apache.zookeeper.ZooKeeper
implements org.apache.zookeeper.Watcher

Provide a zookeeper client to handle session expire. Note this is copied from BK ZooKeeperClient class. The only addition here is that it allows to specify read-only mode which we use when connecting to global ZK. TODO: Remove this class once BK-4.8 is released to include read-only in ZooKeeperClient.
