Zookeeper

ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All these services are used in some form or other by distributed applications. Each time the services are implemented, a lot of effort goes into fixing the bugs and race conditions that are inevitable. As a result, the applications initially usually skimp on the services, which makes them brittle in the presence of change and difficult to manage. ZooKeeper aims at distilling the essence of these different services into a very simple interface to a centralized coordination service. The service itself is distributed and highly reliable.

Prerequisite

For virtual machines, install the Linux agent.
