Installing and Upgrading Sentry for Policy File Authorization

Sentry stores the configuration as well as privilege policies in files. The sentry-site.xml file contains configuration options such as group association provider, privilege policy file location, and so on. The policy file contains the privileges and groups. It has a .ini file format and can be stored on a local file system or HDFS.

Sentry is plugged into Hive as session hooks which you configure in hive-site.xml. The vsentry package must be installed; it contains the required JAR files. You must also configure properties in the Sentry Configuration File.
