> Hi,
> i've got some problems while creating schemas with cql 3.0. After that i can't even start
cassandra anymore.
> Following steps for reproduction were done on a new installation of cassandra:
> 1. simply create a keyspace test via "cqlsh -3"
> create keyspace test with strategy_class = 'SimpleStrategy' and strategy_options:replication_factor
= 1;
> 2. add cf with composite columns via "cqlsh -3"
> create table test1 (
>     a int,
>     b int,
>     c int,
>     d int,
>     primary key (a, b, c)
> );
> 3. drop column family 
> drop columnfamily test1;
> So until now everything went fine. Now i'm trying to insert a slightly modified column
family with the same name above.
> 4. create new cf via "cqlsh -3"
> create table test1 (
>     a int,
>     b int,
>     c int,
>     primary key (a, b)
> );
> This creation fails with following exception:

> Actually it's the result of a slightly different problem in combination with composite
columns, but i will describe this later.
> I've got no idea, what the problem is, there might be some corruption in table schemas,
even after dropping tables.
> I have to delete cassandra data in order to get cassandra running again.
> Best Regards
