6.15. Hive Level Security with Apache Ranger#
Apache Ranger offers comprehensive security for Hadoop. Using the Apache Ranger web console, you can manage policies for access to data for authenticated users and applications such as Presto.
SEP can use Apache Ranger for role-base access control enforcing the same and existing privileges granted on Hive objects. Presto will enforce privileges assigned to Hive Databases, Tables, and Columns. If a user does not have a privilege to query an object, the query will fail and an error will be returned.
Before You Begin#
Before you configure Presto with Apache Ranger, verify the following prerequisites:
Hortonworks Data Platform (HDP) 2.6+ with Apache Ranger and Apache Hive installed.
If you’re not using HDP, then Apache Ranger 0.7.1+ must be installed.
Presto Coordinator and Presto Workers have the appropriate network access to communicate with the Apache Ranger Service. Typically this is port 6080 or 6182, if SSL is used.
If you are new to Apache Ranger, Hortonworks provides excellent documentation for installing and configuring Apache Ranger:
When a query is submitted to Presto, Presto parses and analyzes the query to understand the privileges required by the user to access a particular object. Presto communicates with the Apache Ranger Service to determine if the request is valid. If the request is valid, the query continues to execute. If the request is invalid, an error is returned to the user.
Caching is also used to improve performance and reduce the number of requests to the Ranger service.
Configuring Presto with Apache Ranger#
Apache Ranger Configuration#
There needs to be sys admin Ranger user (user with role
matches Presto Kerberos principal
ranger.kerberos-principal or Ranger Presto
ranger.presto-plugin-username and password
BASIC auth is used.
Presto Kerberos principal is translated to Ranger user name via
auth-to-local hadoop rules from
Presto Configuration for Apache Ranger#
SEP must be configured to enable Presto to communicate with the Apache Ranger service. To enable set the following property in the Hive connector configuration.
hive.security = ranger
Once Apache Ranger is enabled for Presto, there are additional required and optional properties to further configure.
In addition to enforcing the policies in Apache Ranger, Presto also integrates with:
Apache Ranger Key Management Service
row level filtering
tag based policies
support for AWS Glue Data Catalog
Presto only enforces the Apache Ranger policies. Presto does not support any modification of authorization policies in Ranger. This includes commands like CREATE ROLE, GRANT, or REVOKE. If you need to modify the roles and privileges, that must be done via Apache Ranger UI.
Authorization information cannot be accessed by querying the following tables
