Leader server in the cluster to exchange information on the port; D means that in case the Leader server in the cluster hangs, a port is needed to re-elect , select a new Leader, which is the port that the server communicates with each other when the election is performed. If it is a pseudo-cluster configuration, because B is the same, so different Zookeeper instance communication port numbers can not be the same, so they should be assigned a different port number.Use Vim to modify Zoo2.cfg's d

Zookeeper provides high-performance services for distributed applications and is widely used in many common cluster services, most commonly in hbase clusters, as well as in SOLR clusters, and HA automatic failover in Hadoop-2. This article mainly describes the process of deploying zookeeper clusters for hbase clusters, and explains the problems encountered during deployment. By default, the start and stop of zookeeper is managed by HBASE, and if you want to modify this default behavior, you need

, but also greatly improves the efficiency of the experiment. This way of building is simple, low cost, suitable for testing and learning, if your hand machine is not enough, you can deploy 3 servers on one machine.With 3 servers deployed on a single machine, it is important to note that each configuration document we use in the cluster for distributed mode simulates a machine, that is, a single machine and multiple zookeeper instances running on it. However, you must ensure that the individual
