.　　Scenario Three : Configuration management. In the distributed system, we will deploy a service application to n servers, the configuration files are the same (for example: I designed the distributed site framework, the server has 4 servers, 4 servers are the same, the configuration files are the same), If configuration options change, then we have to change each of these configuration files, if we need to change the number of servers less, these operations are not too cumbersome, if we have m

I. INTRODUCTIONZookeeper is a distributed, open source distributed application Coordination Service that is an open source implementation of Google's chubby and an important component of Hadoop and HBase. It is a software that provides consistent services for distributed applications, including configuration maintenance, domain name services, distributed synchronization, group services, and so on.The goal of zooke
