Hadoop2.x(yarn)分布式安装与配置
(1)服务器准备
192.168.119.130 gp-master # NameNode,ResourceManager
192.168.119.131 gp-slave1 # SecondaryNameNode,NodeManager,DataNode
192.168.119.132 gp-slave2 # NodeManager,DataNode
192.168.119.133 gp-slave3 # NodeManager,DataNode
(2)安装java，及ssh免密配置
(3)新建文件夹
/home/gpadmin/hadoop/data/hdfs/data
/home/gpadmin/hadoop/data/hdfs/name
/home/gpadmin/hadoop/data/hdfs/tmp
(4)解压hadoop
/home/gpadmin/hadoop/hadoop-2.6.0
(5)配置文件修改
修改以下文件的java路径
/home/gpadmin/hadoop/hadoop-2.6.0/etc/hadoop/yarn-env.sh
/home/gpadmin/hadoop/hadoop-2.6.0/etc/hadoop/hadoop-env.sh
