According to the ZooKeeper documentation

You will want to have a supervisory process that manages each of your ZooKeeper server processes (JVM).

Exhibitor is a Java supervisor system for ZooKeeper. It provides a number of features:

• Watches a ZK instance and makes sure it is running
• Performs periodic backups
• Perform periodic cleaning of ZK log directory
• A GUI explorer for viewing ZK nodes
• A rich REST API

Requirements/Prerequisites

• It’s assumed that you are familiar with ZooKeeper and the basics of administering it (see the ZooKeeper Administrator’s Guide for details).
• Exhibitor is a Java-based application
• Exhibitor is designed to be run on Unix/Linux based systems (as is Apache ZooKeeper).
• The java CLI tool jps must be in the command line PATH.

Important Facts About Exhibitor

• Exhibitor manages your zoo.cfg and myid files. Do not edit these manually as Exhibitor will overwrite them.
