Hadoop Gateway with Sentry

From this video you will see how the Hadoop Gateway will work with Sentry permissions:

• Log into beeline to show that role testrol1 (assigned to testusers group) has been granted all privileges for testdb5
• See that role betarol1 (assigned to betausers group) has been granted all privilege for testdb6
• See that HadoopGateway has been started with betauser1
• File inside of user/hive/warehouse/testdb6 can be published and file in user/hive/warehouse/testdb5 will fail to publish
• Stop Hadoop Gateway and restart as testuser1
• File inside of user/hive/warehouse/testdb6 can be published and file in user/hive/warehouse/testdb5 will fail to publish. 

Enabling Sentry in your Hadoop Cluster
Sentry allows Big Data Cluster admins to easily grant/revoke permissions to users and groups of users in their organizations. Privileges set in Sentry will then be enforced by Hive, Impala, or HDFS services when a user attempts to execute requests against tables or files.  
 
Starting in CDH 5.3, Apache Sentry integration with HDFS saves admins a lot of work by centralizing access control permissions across components that utilize HDFS. The following website can step you through the necessary steps to enable Sentry.
