Cassandra SE: Cryptic error message on SELECT from a badly formed table

        Details

          Description

          I create a valid column family:

          cqlsh:manual_test> create columnfamily cf1 ( rowkey int primary key, a int );

          Then I create a Cassandra table which only has a column for rowkey, but not for `a`. I expected it to fail, but it works all right:

          create table t1 (rowkey int primary key) engine=cassandra keyspace='manual_test' column_family='cf1';
# Query OK, 0 rows affected (0.12 sec)

          Then I insert into the table. I thought now it would fail for sure, but it worked too:

          insert into t1 values (1);
# Query OK, 1 row affected (0.00 sec)

          Then I selected from the table. Since all the above worked, I thought it would work also, but it didn't:

          select * from t1;
# ERROR 1928 (HY000): Internal error: 'Default TException. [predicate column_names and slice_range may not both be null]'

          The error message is anything but clear, I can only guess what it's about because I made the mess myself. Since the table is basically non-functional, maybe it makes sense to forbid creating it in the fist place.
