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.
