Apache ZooKeeper is an open-source server for highly reliable distributed coordination of cloud applications.[2] It is a project of the Apache Software Foundation.
ZooKeeper is essentially a service for distributed systems offering a hierarchical key-value store, which is used to provide a distributed configuration service, synchronization service, and naming registry for large distributed systems (see Use cases).[3] ZooKeeper was a sub-project of Hadoop but is now a top-level Apache project in its own right.
