----------------------------------------------------------------

I don't think recreating a cluster is a good enough solution for this. I have the same problem
and can't recreate an empty cluster.

Is there a way to prune deleted keys from the system keyspace? I can still list deleted keyspaces
from the schema_keyspaces CF in the system keyspace, perhaps that's what causes problems.

I could create a keyspace with the same name, but different case before, but this doesn't
work anymore:


[default@unknown] create keyspace test_Campaigns with placement_strategy = 'NetworkTopologyStrategy'
and strategy_options = {DC_KOT : 1, DC_DELO : 1, DC_OFC : 1} and durable_writes = true;
62979db5-8643-31ad-b13a-289e66d8f414
Waiting for schema agreement...
... schemas agree across the cluster
NotFoundException()

> I've been trying to define a keyspace from the cassandra-cli on a cluster of 5 nodes
(1.1.0), but I got a NotFoundException(), after a schema agreement accross the cluster message,
which I guess It can be quite confusing, because the keyspace wasn't created at all.
> [default@unknown] create keyspace 'MY_NEW_KEYSPACE' with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy'
and strategy_options = {replication_factor:2} ;
