Problem when deleting a keyspace

[Thierry Templier]

Hello,

I have a problem when trying to delete a keyspace using cqlsh. It seems 
to remain existing even after executing a drop keyspace command:

cqlsh> use teststore;
cqlsh:teststore> drop keyspace teststore;
cqlsh:teststore>describe keyspace teststore;

CREATE KEYSPACE teststore WITH strategy_class = 'SimpleStrategy'
  AND strategy_options:replication_factor = '3';

USE teststore;

CREATE TABLE TestEntity (
  pk text PRIMARY KEY,
  name text
) WITH
  comment='' AND
  comparator=text AND
  read_repair_chance=0.100000 AND
  gc_grace_seconds=864000 AND
  default_validation=text AND
  min_compaction_threshold=4 AND
  max_compaction_threshold=32 AND
  replicate_on_write='true' AND
  compaction_strategy_class='SizeTieredCompactionStrategy' AND
  compression_parameters:sstable_compression='SnappyCompressor';

Is there something else to do in order to actually delete the keyspace?
Thanks very much for your help!
