Error in web ui hadoop related to webhdfs

Question

I am using a single-node hadoop version release-3.3.1-RC3. In web ui hadoop under utilities -> browse the file system it is possible to view the contents of the file (beginning and end) directly in the browser. But instead I get the error Couldn't preview the file. NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'http://desktop-ht79hb0.:9864/webhdfs/v1/user/lemit/output/part-r-00000?op=OPEN&namenoderpcaddress=localhost:9000&length=32768&offset=0&_=1674670084685'. , but with hdfs dfs in the console I can view the contents of the file.

What I tried: followed the link to the error (didn't help), changed the port (didn't help), changed the /etc/hosts file (didn't help) What I expected: the ability to view the file using webhdfs in a browser

Answer 1

1. Change /etc/hosts file
2. Change C:\Windows\System32\drivers\etc\hosts
3. Change hdfs-site.xml, add the property:

   <property>
       <name>dfs.webhdfs.enabled</name>
       <value>true</value>
   </property>
