    Description

      If you use static columns, as implemented in CASSANDRA-6561, then very simple SELECT...WHERE...IN queries fail with an internal NPE.

      create table foo (x text, y text, s text static, primary key (x,y));
      insert into foo (x,y,s) values ('a','b','c');
      select * from foo where x='a' and y in ('b','c');
      Request did not complete within rpc_timeout.
