I work on Apache Trafodion and have been asked to evaluate integration of 
Trafodion with Sentry.
My background includes supporting privileges for Trafodion and am very familiar 
with the basics of users, roles, privileges, and groups.
I read through much of the documentation from the Sentry site but have many 
questions.

First off, I wanted to just install Sentry and play with it a bit to see how 
things work.  I did install it through Cloudera manager but not sure how to 
proceed.

I plan to load some Hive tables and check out how the interface works between 
Hive and Sentry.  As part of Sentry install, does the Hive plug-in get 
installed or is there a separate step required for this.  I did notice that 
beeline was required.

I looked through the section on Kafka integration with Sentry found on the 
Sentry site but I would really like to see a more high level description on 
what is required to integrate with Sentry.  From a high level, it looks like I 
need to add a plug-in that calls some set of API's.  It also looks there they 
may be changes required in Sentry itself.  If there is some kind of check list 
and steps needed for this work, that would be helpful.
