I am building a data ingestion process of loading csv files from local storage to hdfs and then use hive to clean data and then load clean data files into HBase. In my dev environment Ranger has not been added to Ambari yet. I did not create any new users either and only used users like root, hive, and hdfs. I ran into "Permission Denied" issue from time and time. I feel I have to use Ranger, because Ranger is a framework of comprehensive data security across the Hadoop platform. So if I want to make one user, like "root" to be the super user in my dev environment without ever running into "Permission Denied" error again, Ranger is the place to make all the configuration change. Am I on the right track?
