### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement. ### Description ## 目前zookeeper的作用 1. 存储master和worker的服务相关信息,所在主机IP、端口、cpu负载等等 2. master和worker健康检测 3. master故障切换 4. 分布式锁 ## zookeeper带来的问题 1. 增加系统部署和运维的复杂度。 部署DS集群的同时, 还要部署一套zookeeper集群。还要能同时监控运维DS集群和zookeeper集群 1. 增加出错机率。DS集群和zookeeper集群之间网路出现抖动, 有可能出现错误。 ## 移除zookeeper的有点 1. 部署架构更简单 2. 维护成本更低 3.不再因为zookeeper集群出错导致DS报错 ## 移除zookeeper方案 <img width="700" alt="image" src="https://user-images.githubusercontent.com/13765310/178137541-39521953-39f9-40ff-9008-df983e66d1b8.png";> 1. 参考Kafka的KRaft方案,实现master之间的leader选举和数据同步 2. worker server向leader master注册和并与master保持心跳 3. Api server从leader master获取集群信息 ### Use case _No response_ ### Related issues #6680 ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
