Scenario 1: Reusing old data Scenarios This is a practical upgrade scenario, which is to reuse the old version of the data, ZK cluster topology, configuration files are unchanged, only the startup program is the latest version. Reference article: Zookeeper cluster is how to upgrade to a new version of Scenario 2: Re-establish the data scheme the idea is to stop

Recently in the development of Dubbo services have been using the ZK platform provided by the company, because the use of too many people or no maintenance is always a problem, resulting in Dubbo services occasionally can be adjusted, occasionally adjust the situation, so take a moment to deploy a set of their own, the back of the problem is convenient to see the log troubleshooting.1 download package upload Linux Server zookeeper-3.4.6.tar.gz2 Decomp

Both this article and the previous article are true distributed installation configurations and can be directly used in the production environment. For zookeeper installation, refer

Cluster mode configuration and pseudo-cluster are basically consistent.Because the server is deployed on different machines in cluster mode, the CONF/ZOO.CFG files for each server can be identical.Example:ticktime=2000Initlimit=5synclimit=2Datadir=/opt/zk/zk/dataDatalogdir=/opt/zk/zk/logsclientport=2181server.0=192.168.10.128:5555:6666server.1=192.168.10.129:5555

Introduction Recently, with the need for scientific research, Hadoop clusters have been built from scratch, including separate zookeeper and HBase. For Linux, Hadoop and other related basic knowledge is relatively small, so this series of sharing applies to a variety of small white, want to experience the Hadoop cluster. At the same time, put forward some problems encountered in the process of building a
