I still have one open issue: My cluster has only 3 local nodes with 1 CF (5 rows). The initial start works fine. I can see the replicated data and can do all admin tasks I want, successfully.
Now I'm simulating a node failure by stopping Cassandra. I remove (a) commit log (b) content in system keyspace (c) application cf When I bring the node back up I can see the new token assignment, streaming notification (we are talking about 5 rows in 1 cf). Thrift port is not available for ~30 min. Why is that? I would expect it to be back in a matter of maybe <1' (this should be data quantity related).

It looks as if the replication factor is still 1, not 3. This means that each key lives only on one node. By increasing it to 3, data will be replicated across all 3 nodes. Gary.
