瀏覽文件系統鏈接 - hadoop - localhost鏈接

Question

我在Ubuntu上使用Hadoop 2.2。

我可以在我的瀏覽器中加載此鏈接。

http://[my_ip]:50070/dfshealth.jsp

從那裏，當我點擊「瀏覽文件系統」的鏈接，我在這裏邊我想我要my_ip，而不是本地主機和127.0送到

http://localhost:50075/browseDirectory.jsp?namenodeInfoPort=50070&dir=/&nnaddr=127.0.0.1:9000

.0.1

此外，如果我手動鍵入

http://my_ip:50075/browseDirectory.jsp?namenodeInfoPort=50070&dir=/&nnaddr=my_ip:9000

它仍然不起作用。

my_ip是一個外部/全球知識產權貫穿整個問題的文本。

我該如何得到這個工作？我想要的只是能夠從瀏覽器瀏覽我的HDFS文件系統。

芯-site.xml中

<configuration>

<!--

Answer 1

在您的HDFS-site.xml中，通過

<property> 
    <name>dfs.namenode.http-address</name> 
    <value>localhost:50070</value> 
</property> 

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

更換

<property> 
    <name>dfs.http.address</name> 
    <value>my_ip:50070</value> 
</property> 

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

但通常，在僞ditributed模式下，它沒有必要指定這些屬性。
更改屬性後重新啓動羣集。
