To enable Ranger authorization for HDFS on the same cluster we should not select the Ranger service dependency but we should select the 'Enable Ranger Authorization' checkbox instead of the Ranger service under HDFS. In the base cluster, even if you select / check the box for "Ranger_service", the CM seem to indicate saving configuration successfully, but that box will never be checked, and a warning message will be logged in CM server logs indicating "CyclicDependencyConfigUpdateListener - Unsetting dependency from service hdfs to service ranger to prevent cyclic dependency". Refer the below article which is for Solr-Ranger dependency. https://my.cloudera.com/knowledge/WARN-quotUnsetting-dependency-from-servicequot-when-Ranger?id=329275

I'm glad to announce that finally i have solved my issue. Thanks again for the community support received. I would like to explain the workaround applied hoping to be useful for other guys affected by same issue. The issue was related to a missing authentication by ranger. I don't understand why the solution "Policy ranger in Kudu" described here https://docs.cloudera.com/cdp-private-cloud-base/7.1.8/kudu-security/topics/kudu-ranger-policies.html doesn't work. Anyway ..... So i decided to follow this guide "Specifying trusted users" ( https://docs.cloudera.com/cdp-private-cloud-base/7.1.8/kudu-security/topics/kudu-security-trusted-users.html ) By cloudera manager (kudu service) i set following properties "Master Advanced Configuration Snippet (Safetz Valve) for gflagfile" to this value: --trusted_user_acl=impala,hive,kudu,rangeradmin,nifi then i restarted kudu. After this settings, command work fine sudo -u nifi kudu table describe nautilus-bigdata-h02 default.gianni TABLE default.gianni ( id INT64 NOT NULL, name STRING NULLABLE, PRIMARY KEY (id) ) OWNER hueadmin REPLICAS 1 COMMENT even NIfi PutKudu processor work fine and i can write my row on the table. Thanks to all !!

Hey Matt! I am truly grateful for your answer. You made me realize what I was doing wrong and I learned a lot while reading trough your explanation. I am going to revise the documentation again, as I am realizing that I did not had some concepts crystal clear before. Thanks again and I wish you a good day.
