Issue with HUE

prakashpunj — Tue, 21 Apr 2026 13:50:31 GMT

Successfully installed HUE and modified all the parameter in HUE.INI such as webhdfs_url and set the parameter in HDFS configuration (proxyuser) and enabled webhdfs, But HUE is not able to connect to HDFS file system. It's trying at the URL: http://localhost:50070/webhdfs/v1 BUT correct hostname is listed in hue.ini. 

it doesnt seem to read the configuration from hue.ini. INI.

below is what I am getting from HUE web interface. 

Potential misconfiguration detected. Fix and restart Hue.


hadoop.hdfs_clusters.default.webhdfs_url	Current value: http://localhost:50070/webhdfs/v1/

@Prakash Punj

You say "modified all the parameter in HUE.INI". Does it mean you manually made those changes? If so, have you restarted Hue to account for the new changes? Look also at the ownership of the file. It may not be owned by Hue if you made the changes under a different account. If after restart, you still have the issue, are you pointing to the server that runs the Hive2 Server?

If helpful, vote/accept response.

Thank you @Constantin Stanca @Neeraj Sabharwal

I manually made the change in HUE.INI to point to correct hiveserver2 and namenode/resource manager, also restarted HUE multiple times.

Please take a look at the ownership of HUE.INI file (root/root). I am using root account

Take a look at the HUE.INI which has entry for webhdfs_URL. it;s pointing to correct namenode

Also check the screenshot of the error I am getting.

Thanks

Can you please check the contents of hue_original.ini and see if it is pointing to localhost?

If yes, move/remove the file from /etc/hue/conf folder, restart hue and then try.

@Prakash Punj

Could you publish your hue.ini files as text? The screenshots provided are a bit difficult to read and I would like to see the actual content.

Side question: which version of OS and HDP you use? Hue on Centos 7 and HDP 2,4 is not supported.

@Constantin Stanca

I uploaded the Hadoop cluster configuration section from HUE.INI. please take a look.

@Sindhu

hue_original.ini is the original copy of hue.ini which I made before modifying hue.ini with hadoop cluster information.

@Constantin Stanca & @Sindhu

Thanks guys problem solved. Actually hue_original.ini file was causing the problem. I made this copy to save the original comfiguration but HUE when it gets restarted, it reads all the INI files for configuration. I changed that file to .TXT and now HUE passes all the configuration.

thanks

@Prakash Punj

Good lesson learned for all of us. It is a good practice to save a file with a name like hue.ini.old for anything unix. Hue is not the only that reads all .ini files from a directory.
