Examples of ZkClient

com.linkedin.helix.manager.zk.ZkClient
ZKClient does not provide some functionalities, this will be used for quick fixes if any bug found in ZKClient or if we need additional features but can't wait for the new ZkClient jar Ideally we should commit the changes we do here to ZKClient. @author kgopalak
org.I0Itec.zkclient.ZkClient
Abstracts the interaction with zookeeper and allows permanent (not just one time) watches on nodes in ZooKeeper
org.apache.activemq.leveldb.replicated.groups.ZKClient
org.apache.hadoop.yarn.lib.ZKClient
ZK Registration Library currently does not use any authorization
