Hi,

I've added table level security using spark extensions based on the ongoing work proposed for ranger inĀ RANGER-2128. Following the same logic, you could mask columns and work on the logical plan, but not filtering or skipping rows, as those are not present in these hooks.

The only difficult I found was integrating extensions with pyspark, since in python the SparkContext is always created through the constructor and not using the scala getOrCreate() method (I've sent an email regarding this). But other than that, it works.

Hi,

I'd like to implement some kind of row-level security and am thinking of adding additional filters to the logical plan possibly using the Spark extensions.
Would this be feasible, for example using the injectResolutionRule?

thanks in advance,
RichardĀ
