1. 解压hadoop
tar -zxvf hadoop-2.6.0-cdh5.7.0.tar.gz -C ~/app/
2. 配置文件位置
/home/hadoop/app/hadoop-2.6.0-cdh5.7.0/etc/hadoop
3. hadoop-env.sh
export JAVA_HOME=/home/hadoop/app/jdk1.7.0_51
4. core-site.xml
- /home/hadoop/app/tmp提前创建一下
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://hadoop001:8020</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/hadoop/app/tmp</value>
</property>
</configuration>
5. hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>
6. 格式化HDFS
- 只做一次；
bin/hdfs namenode -format
7. 启动HDFS
[hadoop@hadoop001 sbin]$ ./start-dfs.sh
18/07/10 05:42:56 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

8. 查看启动结果
[hadoop@hadoop001 sbin]$ jps
154 NameNode
272 DataNode
429 SecondaryNameNode
642 Jps
注：
HDFS的Web页面的管理端口是50070，把当前容器重新commit成个镜像，run的时候把端口映射出去，从宿主机就可以访问了，localhost:50070；
