Good question... there is enterprise version of apache kylin (try google)
with row-level-security implemented, that works with Hive / Ranger
out-of-box.

If want to work on your own implementation, I think the entry point must be
OLAPContext.IAccessController, where the check method is invoked before a
query execution plan begin to execute.


Cheers,
