Some of the users who access our cluster are trying to access HDFS. However when they try accessing HDFS they get permission denied error on production cluster. Below are the steps I am planning to implement in Ranger :
1. Since Ranger plugin is enabled, I will add a policy.
2. Mention the path which I need to provide access to
3. Add there userid's and type of access and save.
However problem is the users whom I want to add are not showing up in the list of users. Can we go ahead and manually add the users in Ranger and then provide access?
Request you guys help to validate it. or is there anything else I have to take care before doing these?
