在ubuntu中访问浏览器上的hadoop

Question

我在伪分布式模式下对Hadoop安装的参考是hadoop_environment_setup。我正在使用Hadoop 2.7.0和Ubuntu 14.04.2 LTS。 我可以通过http://localhost:8088/cluster/nodes验证群集的所有应用程序，如下面的screenhost所示。

我的主机文件，即/ etc / hosts包含以下映射：

127.0.0.1   localhost
127.0.1.1   subash-HP-Pavilion-dv4-Notebook-PC

现在，当我尝试通过http://localhost:50070/在浏览器上访问Hadoop时，我得到的网页不可用消息。

现在正在运行

start-dfs.sh

我收到以下错误：

WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
    Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.
    Starting namenodes on []

然后我按如下方式输入hadoop密码：

hadoop@localhost's password: 
localhost: starting namenode, logging to /home/hadoop/hadoop/logs/hadoop-hadoop-namenode-subash-HP-Pavilion-dv4-Notebook-PC.out
hadoop@localhost's password: 
localhost: starting datanode, logging to /home/hadoop/hadoop/logs/hadoop-hadoop-datanode-subash-HP-Pavilion-dv4-Notebook-PC.out
Starting secondary namenodes [0.0.0.0]
hadoop@0.0.0.0's password:

输入密码后，会抛出以下错误：
