Hello!

I have a 6 nodes Cloudera 5.7 kerberized cluster, and I'm trying to manage sentry roles with hue, but when I try to manage them, I only can see the databases.

I have enabled sentry with cloudera manager as shown in this documentation: http://www.cloudera.com/documentation/enterprise/latest/topics/cm_sg_sentry_service.html

If I try to run a query I get the following error:

Your query has the following error(s):
Error while compiling statement: FAILED: SemanticException No valid privileges User hive does not have privileges for SWITCHDATABASE The required privileges: Server=server1->Db=*->Table=+->Column=*->action=insert;Server=server1->Db=*->Table=+->Column=*->action=select;

I tried granting select and ALL permissions to the usergroup in the database.. and the error persist.. And I also still unavailable to grant permissions on tables.

Any clue with what may be happening?

Thank you in advance!

Here is the configuration of my cluster

I finally solved it
The problem was that I had no role at all, and roles created by hue didnt work for some reason.

So I created an admin role via beeline:

Obtained hive ticket
kinit -k -t run/cloudera-scm-agent/process/218-hive-HIVESERVER2/hive.keytab hive/node01.test.com@TEST.COM
Connected to hive with beeline using hive keytab.
beeline>!connect jdbc:hive2://node01.test.com:10000/default;principal=hive/node01.test.com@TEST.COM
Created the role admin.
beeline>Create role admin;
Granted priviledges to admin role.
GRANT ALL ON SERVER server1 TO ROLE admin WITH GRANT OPTION;
Assign the role to a group.
GRANT ROLE admin TO GROUP administrators;

After these steps all users within the group administrators are allowed to manage hive priviledges
