远程访问HDFS [英] Accessing HDFS Remotedly

问题描述

我的hadoop服务器在某些服务器上运行，例如在IP 192.168.11.7上运行 并具有如下所示的core-site.xml:

I have hadoop server runs on certain server, let's say on IP 192.168.11.7 and have its core-site.xml as follows :

<configuration>
<property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
</property>

我已经运行了hdfs，即使用命令:

I already run my hdfs, i.e. with command :

sbin/start-dfs.sh

现在，我想使用浏览器从本地计算机访问HDFS.有可能吗?

Now, I want to access the HDFS from my local computer with browser. Is it possible?

我尝试了 http://192.168.11.7:9000 或

I tried http://192.168.11.7:9000 or http://192.168.11.7:50075, but no avail. i.e. This site can’t be reached

非常感谢您

这是我的hdfs-site.xml的内容:

This is the content of my hdfs-site.xml :

<configuration>
<property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
<property>
    <name>dfs.webhdfs.enabled</name>
    <value>true</value>
</property>
<property>
    <name>dfs.namenode.http-address</name>
    <value>0.0.0.0:50070</value>
</property>

和我的core-site.xml:

and my core-site.xml :

<configuration>
<property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
</property>

<property>
        <name>dfs.datanode.http.address</name>
        <value>0.0.0.0:50075</value>
</property>

但是当我从本地计算机访问它时: http://192.168.11.7:50075 仍然没有有用的 有什么问题吗?

but when I access it from ly local computer : http://192.168.11.7:50075, still no avail Is there something wrong?

谢谢

推荐答案

请注意:

<property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
</property>

不适用于用户及其浏览器.当需要访问HDFS时，Java程序会读取该值. 您正在寻找的是此键:

is not for users and their browsers. This value is read by Java programs when need to access HDFS. What you are looking is this key:

<property>
        <name>dfs.datanode.http.address</name>
        <value>0.0.0.0:50075</value>
</property>

这是datanode公开其状态的地方. 要使用网络浏览器浏览HDFS，您需要激活webhdfs.

This is where the datanode exposes its status. To surf into HDFS using a web browser you need to activate webhdfs.

<property>
  <name>dfs.webhdfs.enabled</name>
  <value>true</value>
</property>
<property>
  <name>dfs.namenode.http-address</name>
  <value>0.0.0.0:50070</value>
</property>

进入hdfs-site.xml

into hdfs-site.xml

然后转到http://hostname:50070以从那里访问webHDFS UI，您可以检查所有内容.

then go to http://hostname:50070 to access webHDFS UI from there you can check everything.
