> This is an issue I first noticed through the C# driver, but I was able to repro on cqlsh, leading me to believe this is a Cassandra bug.
> Given the following schema:
> {noformat}
> CREATE TABLE "TestKeySpace_4928dc892922"."coolMovies" (
>     unique_movie_title text,
>     movie_maker text,
>     director text,
>     list list<text>,
>     "mainGuy" text,
>     "yearMade" int,
>     PRIMARY KEY ((unique_movie_title, movie_maker), director)
> ) WITH CLUSTERING ORDER BY (director ASC)
> {noformat}
> Executing a SELECT with FILTERING on a non-PK column, using a NULL as the argument:
> {noformat}
> SELECT "mainGuy", "movie_maker", "unique_movie_title", "list", "director", "yearMade" FROM "coolMovies" WHERE "mainGuy" = null ALLOW FILTERING
> {noformat}
> returns a ReadFailure exception:
> {noformat}
> cqlsh:TestKeySpace_4c8f2cf8d5cc> SELECT "mainGuy", "movie_maker", "unique_movie_title", "list", "director", "yearMade" FROM "coolMovies" WHERE "mainGuy" = null ALLOW FILTERING;
