（九）启动集群
1、重启格式化HDFS

hdfs namenode -format

2、启动文件系统

start-dfs.sh

3、启动文件系统报错配置JAVA_HOME

看我上一篇博客配置jdk

4、启动文件系统

start-dfs.sh

5、启动YARN

start-yarn.sh

6、访问

http://localhost:50070

7、访问50070端口失败手动配置端口

8、测试HADOOP

9、关闭服务

<span class="token variable">Stop-all</span><span class="token punctuation">.</span><span class="token variable">sh</span>

 

10、查看DATANODE信息

<span class="token variable">jps</span>

 

（十）测试服务

1、Brower Directort 报错则更改jdk1.8版本就可以了

2、Hdoop上传文件以及查看状态

可以采取界面操作

h’d’f’s dfs -put 你文件的路径

3、测试上传以及下载文件

建议采用界面操作
