Unfortunately, the roles in Hive are advisory only. Effectively everyone is an admin who can grant anyone (including themselves) additional permissions.
If you need security, the best option is to protect the HDFS directories that the data is stored in. Set the HDFS owner, group, and permissions so that the users have read/write permission as desired. Don't forget to set things at both the database directory and table directory levels. Then you need to configure hive.security.metastore.authorization.manager with org.apache.hadoop.hive.ql.security.authorization.StorageBasedAuthorizationProvider, which uses HDFS permissions to control access to databases and tables. By setting it up this way, the HDFS permissions will be enforced by the NameNode and keep each group from reading each others data. The metastore will use the same HDFS permissions to prevent access to the other groups databases' metadata. Of course, all of this assumes you have Kerberos turned on for your Hadoop cluster. It also requires a minimum of Hive 0.10.
