HUE Homedirectory Creation Failed.

Question

Hello,

we have a a CDH5.16.2 Cluster with Hue connected to ActiveDirectory.

We can login and access Hive as an example.

But the automatic creation of a user is not working.

The error Message is :

[09/Jan/2020 17:57:10 +0100] views ERROR Could not create home directory at login for *****.

For me it looks like that "root" want create the homedir but root has no rigths.

We also set dfs.permissions.supergroup, dfs.permissions.superusergroup to another value so admins came from AD.

We dont use kerberos at the moment.

Hi

thanks for your Message. I found the Problem, after removal of Kerberos from the Cluster someone set Root:supergroup on /.

I change ist back to hdfs:<amingroup> and now hue can create Homedirs.

CM doesn't have that capability as compared to Ambari where you simply add the ambari.post.user.creation.hook=/var/lib/ambari-server/resources/scripts/post-user-creation-hook.sh in the /etc/ambari-server/conf/ambari.properties and that auto-creates the user home in HDFS directories.

Contrary if you add users in Hue it presents an option to perform this for you in its user add wizard screen. But there is a nice article you could try out I haven't tested it myself automatically creation of AD user directory in hdfs

Hope that helps, please share your success with the community

Happy hadooping
