What is zookeeper in Apache Mesos?

Apache Zookeeper is an open-source service or software that assists an individual in managing a large group of hosts. To manage and coordinate hosts especially in a distributed environment is not easy but tricky. To make the task easier, an apache zookeeper offers software developers the opportunity to remain focus as they build the software features. This saves them time to think of how distributive their applications are. Through zookeeper, you will maintain group services, configuration information, naming for distributed applications. Apache zookeeper also implements various protocols on the cluster. The application can no longer implement by itself because of this.
