The Ranger RMS ACL-sync feature supports a single logical HMS, to evaluate HDFS access via Hive permissions. Privileges can be granted to roles, which can then be assigned to users. This topic provides instructions for using the Hive metastore connector for Snowflake to integrate Apache Hive metastores with Snowflake using external tables. To define a read-only Hive metastore user, follow these steps. Hive storage based authorization is a remote metastore server security feature that uses the underlying filesystem permissions to determine permissions on databases, tables, and partitions. In this mode, Presto enforces the authorization checks for queries based on the privileges defined in Hive metastore. Add the following required authorization parameters in hive-site.xml to configure storage based authentication: hive.metastore.pre.event.listeners 3) Assign that role to a user or assign table/view level permissions to Users. Must be set to true for the storage based model. You manage user and group privileges through permissions and ACLs in the distributed file system. By enabling Storage Based Authorization in the Metastore Server, you can use this single source for truth and have a consistent data and metadata authorization policy. Use of Storage Based Authorization in metastore is recommended. These resources include databases, tables, connections, and user-defined functions. The policies are maintained under repositories under those projects. The set commands used to change Hive configuration are restricted to a smaller safe set. The HDFS permissions act as one source of truth for the table storage access. The permissions a user or group has on directories in the filesystem determines access to data.

While relying on Storage based authorization for restricting access, you still need to enable one of the security options 2 or 3 listed below or use FallbackHiveAuthorizer to protect actions within the HiveServer2 instance. This is one of the most common use cases of Hive. Only users that have administrative privileges can create or drop roles. Hence this is marked as unstable. However, it allows only one user in embedded mode. When metastore server security is configured to use Storage Based Authorization, it uses the file system permissions for folders corresponding to the different metadata objects as the source of truth for the authorization policy.

The Ranger RMS ACL-sync feature supports a single logical HMS, to evaluate HDFS access via Hive permissions. By default, HDInsight creates a metastore with every cluster type. You can configure Hive SQL standard based authorization in Hive version 1.0 to work with impersonation in Drill 1.1.
