Hi, The Sentry community has recently added a number of features including the DB based policy store and support for Hive's authorization SQL syntax.
I have draft of Sentry architecture overview [1] that I would like to post on the Apache blog. Please take a look and let me know if you have any comments/suggestions. thanks Prasad [1] - https://blogs.apache.org/roller-ui/authoring/preview/sentry/?previewEntry=apache_sentry_architecture_overview
