Discuss Zookeeper

ZooKeeper is a distributed co-ordination service to manage large set of hosts. Co-ordinating and managing a service in a distributed environment is a comppcated process. ZooKeeper solves this issue with its simple architecture and API. ZooKeeper allows developers to focus on core apppcation logic without worrying about the distributed nature of the apppcation.

The ZooKeeper framework was originally built at “Yahoo!” for accessing their apppcations in an easy and robust manner. Later, Apache ZooKeeper became a standard for organized service used by Hadoop, HBase, and other distributed frameworks. For example, Apache HBase uses ZooKeeper to track the status of distributed data. This tutorial explains the basics of ZooKeeper, how to install and deploy a ZooKeeper cluster in a distributed environment, and finally concludes with a few examples using Java programming and sample apppcations.
