Title   The design and accomplishment of a distributed scheduling system based on big data platform

Abstract With the development of Internet, the amount of information and data have been becoming larger。 For the enterprises，consumption of task-computing and data processing also need more and more resources, the performing of task in single computer becomes more difficult, so we need a perfect, reliable and efficient management system to assign and control tasks executing in the distributed cluster uniformly。 This project is based on the Zookeeper framework as the message coordination middleware, and considers the communication connection, load balancing, disaster treatment, condition monitoring, online expansion, data backup, heartbeat detection and other aspects, detailedly research and design a reasonable and stable structure, and the various problems which system will encounter and their solutions, then realize a simple and feasible distributed scheduling system by programming, at the same time through the graphical Web system achieving management and control of timed tasks, users can make simple operation to automatically, efficiently and safely completing the distributed scheduling execution of tasks。
