Configure permissions

After integrating Ranger into Kafka, you can set the relevant permissions.
Notice In a standard cluster, Ranger automatically generates the all - topic rule after the Kafka service is added. This rule indicates that there are no restrictions onpermissions. All users can perform all actions. In this case, Ranger cannot identify permissions through the user.
Here, user_test is used as an example to add the Publish permission:add the Publish permission
After you add a policy, the permissions are granted to the test user. This user can then perform the write operation fortest.
Note The policy takes effect one minute later after it is added.
