Part II , Zookeeper

There are two ZooKeeper server packages:

• The hadoop-zookeeper base package provides the basic libraries and scripts that are necessary to run ZooKeeper servers and clients. The documentation is also included in this package.
• The hadoop-zookeeper-server package contains the init.d scripts necessary to run ZooKeeper as a daemon process. Because hadoop-zookeeper-server depends on hadoop-zookeeper, installing the server package automatically installs the base package.
