> although IN operator is allowed over the last clustering or partitioning columns, the
CQL Query Validator is rejecting queries when they attempt to fetch collection columns in
their result set.
> It seems a similar bug (CASSANDRA-5376) was raised some time ago, and a fix (rather mask)
was provided to give a better error message to such queries in 1.2.4. 
> Considering that Cassandra & CQL has evolved a great deal from that period, it now
seems possible to provide an actual fix to this problem, i.e. allowing queries to fetch collection
columns even when IN operator is used.
