Damien Stevenson commented on CASSANDRA-12757:
----------------------------------------------
I have tested this too and get the same behaviour that [~Gerrrr] has shared
above.
However, I do not think that failing with an AssertionError is the most
appropriate way to handle the case where an incorrect keyspace value is
provided for the allocate_tokens_for_keyspace option. To that end, I have
created a patch that aims better handle this situation.
Please review and let me know if you have any comments.
