What is zookeeper?Apache ZooKeeper is a high-performance coordination server for distributed applications. It exposes public services (such as naming and configuration management, synchronization, and group services) using a simple interface, so that users do not have to start programming from scratch. It provides ready-made support for consensus-building, group management, leader elections, and presence agreements (presence protocol).Here is my exper
