Question
What can I do if an error message shown in the following figure is displayed, indicating that the HDFS file cannot be accessed when I use Hue web UI to access the HDFS file?
Answer
- Check whether the user who logs in to the Hue web UI has the permissions of the hadoop user group.
- Check whether the HttpFS instance has been installed for the HDFS service and is running properly. If the HttpFS instance is not installed, manually install and restart the Hue service.
