i see the following in my server logs quite closely while doing a lot of batch_mutations and reads.  i create keyspaces and column families using thrift api, not cassandra.yaml.  did not migrate anything from 0.6.

4 node cluster, RF = 3, QUORUM read/write.

happens immediately on a fresh start of the cluster with no data - removed all data and commit logs before starting.

i believe the problem is because the creation of the keyspace/CFs has possible not propagated to all nodes before i start slamming with the batch_mutates and gets.  if i put a 1 second sleep after the keyspace has been created, but before i start using it, all is well.
