Error validating LDAP user in Hue
Hive can use LDAP and Kerberos both, if they are enabled on your CDP cluster. By default, Hive uses LDAP to authenticate the Hue service instead of Kerberos. As a result, you may see the following error after logging in to Hue web interface or while trying to access the Hive editor: Bad status: 3 (PLAIN auth failed: Error validating LDAP user).
Additionally, you may not be able to view databases or Hive tables. To resolve
this issue, you can enforce the client connections (between Hive and Hue) to use Kerberos instead of LDAP by configuring the value of the hive.server2.authentication
property to KERBEROS in the Hue hive-site.xml file.
