Hadoop的多节点集群详细启动步骤（3或5节点）

gteric

　　版本1
　　利用自己写的脚本来启动，见如下博客
hadoop-2.6.0-cdh5.4.5.tar.gz(CDH)的3节点集群搭建
hadoop-2.6.0.tar.gz的集群搭建（3节点）
hadoop-2.6.0.tar.gz的集群搭建（5节点）
　　版本2
　　第一步：见zookeeper启动
Zookeeper的多节点集群详细启动步骤（3或5节点）
　　如果namenode启动不起来，就单独启动吧。

[hadoop@HadoopMaster hadoop-2.6.0]$ sbin/hadoop-daemons.sh start namenode

　　第二步：启动hadoop集群

[hadoop@HadoopMaster hadoop-2.6.0]$ sbin/start-all.sh

　　This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
