继上篇 docker系列3：docker搭建cdh单机版， 只有一个节点，若想搭建多节点集群，可以参考官方文档：https://hub.docker.com/r/cloudera/clusterdock

1， 运行脚本：启动容器

# docker-cdh集群：单机模拟多节点
source /dev/stdin <<< "$(curl -sL http://tiny.cloudera.com/clusterdock.sh)"  
 
#两个节点
 clusterdock_run ./bin/start_cluster cdh
 
# 拉取镜像，运行容器

#      -v /tmp/clusterdock \                                                                  
#      -v /etc/hosts:/etc/hosts \                                          
#      -v /etc/localtime:/etc/localtime \                            
#      -v /var/run/docker.sock:/var/run/docker.sock \                
#      "${CLUSTERDOCK_IMAGE}" $@          

#四个节点： cluster in which the containers are named node-1.testing, node-2.testing, node-3.testing, and node-4.testing:
clusterdock_run ./bin/start_cluster -n testing cdh --primary-node=node-1 --secondary-nodes='node-{2..4}'
