Zookeeper cluster (2), zookeeper Cluster
After reading the previous article "zookeeper pseudo cluster 1", I believe you have some knowledge about zookeeper clusters. Next, let's talk about zookeeper real clusters. In fact, the real cluster and pseudo cluster still have many
describes the Zookeeper is based on the stable version of 3.2.2, the latest version can be obtained through the official website http://hadoop.apache.org/zookeeper/, Zookeeper installation is very simple, The installation and configuration of Zookeeper are described in two ways, from stand-alone mode and cluster mode.
The purpose of zookeeper is to encapsulate complex and error-prone key services and to provide users with Easy-to-use interfaces and high-performance, functionally stable systems. Zookeeper has two operating modes, stand-alone mode (Standalone) and cluster mode (distributed), but the zookeeper advantage is that it can build distributed

First, briefStandalone mode is the simplest and most basic mode in the three modes of deploying the Zookeeper service, with just one machine, standalone mode is only available for learning, and standalone mode is not recommended for development and production. This article describes the entire process of deploying a zookeeper server in standalone mode and provides some simple commands to verify that it is r

filesystem-like hierarchical system that stores data in a node, which is called Znode. The znode originates from the Zookeeper data node. Each znode as a directory, can have multiple child nodes, and the hierarchy continues. In order to access the Znode,zookeeper follow the file path similar to the structure. For example, the path to Znode Firstnode and the corresponding child nodes can look like this:/fir

Http://linux-ha.org/wiki/Split_BrainThe split-brain problem is that 1 clusters assume that a network failure has occurred. It is very likely that 1 clusters are divided into two parts. These two parts do not know whether the other side is alive. Do not know whether the networ
