> Running Cassandra 3.0.1 installed from apt-get on debian.
> I had a keyspace called 'tests'. I dropped it. Then I checked some nodes and one of them
still had that keyspace 'tests'. On a node that still has the dropped keyspace I ran:
> nodetools repair tests;
> In the system logs of another node that did not have keyspace 'tests' I am seeing a null
pointer exception:
> {code:java}
