-------------------------------
Folks,
It seems to me that column-level access control is implemented outside of Spark
in spark-llap library. It also looks like the responsibility for making Spark
SQL commands *secure* is the responsibility of the maintainers of LLAP. I'm
making this assumption based on the following PRs which have hardened existing
DESC table command:
https://github.com/hortonworks-spark/spark-llap/pull/18
https://github.com/hortonworks-spark/spark-llap/pull/134
[~dongjoon], could you confirm?
If that's the case, then wouldn't heads-up to [~dongjoon] be sufficient to
unblock attached PR?
