> I'm not sure if this is intended or not, but currently a table's dropped 
> columns are not dropped when the table itself is dropped:
> {noformat}
> cqlsh> create keyspace ks WITH replication={ 'class' : 'SimpleStrategy', 
> 'replication_factor' : 1 } ;
> cqlsh> use ks;
> cqlsh:ks> create table  test (pk text primary key, c1 int);
> cqlsh:ks> alter table test drop c1;
> cqlsh:ks> drop table test;
> cqlsh:ks> select * from system_schema.dropped_columns where keyspace_name = 
> 'ks' and table_name = 'test';
>  keyspace_name | table_name | column_name | dropped_time                    | 
> kind    | type
> ---------------+------------+-------------+---------------------------------+---------+------
>             ks |       test |          c1 | 2017-07-25 17:53:47.651000+0000 | 
> regular |  int
> (1 rows)
> {noformat}
> This can have surprising consequences when creating another table with the 
> same name.
