      Description

      If a table has several data files and some files are empty, Broadcast join with that table returns wrong data.

      select * from customer_large a
       left outer join nation_multifile b on a.c_nationkey = b.n_nationkey
       where b.n_nationkey is null
      

      The above query should return empty rows but return many rows with null n_nationkey value.
