无法连接到http：// localhost：50030 / - Hadoop 2.6.0 Ubuntu 14.04 LTS

我在Ubuntu 14.04 LTS机器上安装了Hadoop 2.6.0。我能够成功连接到 http：// localhost：50070 / 。

I have Hadoop 2.6.0 installed on my Ubuntu 14.04 LTS machine. I am able to successfully connect to http://localhost:50070/.

我试图连接到 http：// locahost：50030 / 我在 mapred-site.xml中有以下内容

<configuration>
    <property>
        <name>mapred.job.tracker</name>
        <value>localhost:9001</value>
    </property>
</configuration>

然而，我仍然遇到无法连接的错误。我运行了jps命令并得到了以下输出：

Yet I continue to get an error of not being able to connect. I ran the jps command and got the following output:

12272 Jps
10059 SecondaryNameNode
6675 org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
10233 ResourceManager
9867 DataNode
9745 NameNode
10362 NodeManager

所以我的名字和数据节点都在运行。

So my name and data nodes are both running.

如果我需要发布任何信息，请让我知道。

If I need to post anymore information please let me know.

谢谢

Thanks
