Policies limit access to Hive and HBase repositories to White Listing users, that is once a repository is created and the agent installed, only users who have been granted permission can access the resources. The Security Agent intercepts requests to the resource and checks the user against the policies of the repository and determines if the user matches any rules that grant them access to the resource.
If no rules explicitly grant access, the following occurs:
HDFS: The request is passed through and the user can access the resource if permitted to do so by the HDFS local policies.
Hive and HBase : The request is rejected.
