Subject Re: AssertionError: Unknown keyspace?

Oh shoot, this is a seed node.  Is there documentation on how to bootstrap
a seed node?  If I have seeds of A, B, C for every machine on the ring and
I am bootstrapping node B, do I just modify cassandra.yaml and remove node
B from the yaml file temporarily and boot it up (Note, I still received
the unknown keyspace errors :( but it is bootstrapping now) and I assume I
can add node B back once all the data is in there.
