Error deploying HDFS Ranger Plugin on Kerberised Cluster

avatar
Contributor

Am creating a new cluster through Ambari using blueprints with version 2.4.1.0 of Ambari and HDP 2.5.0, the cluster is running FreeIPA and is kerberised, Ranger deploys fine and no errors are logged in the Ambari logs for the deployment of Ranger Admin or Ranger Usersync services, however when starting the namenode there are errors logged in the startup and the HDFS service is not created in Ranger Web UI.

Have pasted in the relevant logs below and some of the manual commands I have run on the nodes to try to troubleshoot. Any help would be greatly appreciated.

Namenode startup log stderr in Ambari;

2016-11-04 08:45:26,899 - Error in call for getting Ranger service:
 No JSON object could be decoded
2016-11-04 08:54:10,812 - Error in call for creating Ranger service:
 No JSON object could be decoded
2016-11-04 08:54:10,813 - Hdfs Repository creation failed in Ranger admin

Namenode startup log stdout in Ambari;

Finally spotted my mistake, was the SPNEGO kerberos configuration in Ambari was incorrect, I had the principal set to HTTP/auth-001@PROJECT1 instead of HTTP/_HOST@PROJECT1.
