It sounds plausible that is what we are running into. All of our nodes report a
replication factor of 2 (both using describe, and show schema), even though the
cluster reported that all schemas agree after I issued the change to 4.
If this is related to the bug that you filed, it might also explain why I've
had difficulty changing the compression options on this same cluster. I issue
an update command, schemas agree, but yet the change is not evident.
