We have some troubles getting the filebrowser working in Hue.
HDP was installed through Ambari and the installation guide below was used to install Hue:
When we click the filebrowser icon the following error is displayed:
Failed to obtain user group information: org.apache.hadoop.security.authorize.AuthorizationException: Unauthorized connection for super-user: hue from IP 192.168.0.1 (error 401)
When we click the ‘Check for misconfiguration’ button the following is shown (the value is in fact correct, as I can visit the URL manually):
hadoop.hdfs_clusters.default.webhdfs_url Current value: http://hado001d.hadoop.local:50070/webhdfs/v1/
Failed to access filesystem root
We assumed it to be related to the proxyuser settings, but these seem to be correct, our core-site.xml contains the following (configured through Ambari and all services have been restarted afterward):
We also tried adding specific values to core-site.xml but if we do that we get the ‘could not impersonate’ error message:
Anybody any ideas?
