hadoop-2.2.0
1.下载解压到/opt,文件夹改名hadoop
2./etc/profile.d文件夹下建立hadoop.sh
内容都是根据文档添加的
HADOOP_COMMON_HOME=/opt/hadoop
HADOOP_HDFS_HOME=/opt/hadoop
HADOOP_MAPRED_HOME=/opt/hadoop
HADOOP_YARN_HOME=/opt/hadoop
HADOOP_CONF_DIR=/opt/hadoop/conf
YARN_CONF_DIR=/opt/hadoop/conf
export HADOOP_COMMON_HOME
export HADOOP_HDFS_HOME
export HADOOP_MAPRED_HOME
export HADOOP_YARN_HOME
export HADOOP_CONF_DIR
export YARN_CONF_DIR
3.在HADOOP_HOME文件夹下建立conf文件夹，把HADOOP_HOME/etc/hadoop文件夹下的capacity-scheduler.xml，mapred-site.xml，yarn-site.xml文件拷贝到conf文件夹下
根据帮助文档的内容修改
别忘了yarn-site.xml中
<property>
<name>yarn.nodemanager.address</name>
<value>0.0.0.0:9333</value>
<description>the nodemanagers bind to this port</description>
</property>
port需要填一个真实的port 而不是“port”
4.终端输入 命令在sbin目录
$ yarn-daemon.sh start resourcemanager
$ yarn-daemon.sh start nodemanager
