Does CQL not allow CL=ONE queries? Why does it ask two nodes for the key, when you say that you are using CL=default=1? I'm a bit confused here (I'm a thrift user).
Yup, that's another thing I'm curious about too (default CL is ONE for sure), but as for now it helps me to investigate my problem, I consider it as a feature :>
But thinking about your theory some more: I think CASSANDRA-4905 might make reappearing columns more common (only if you do not run repair within gc_grace of course). Before CASSANDRA-4905 the tombstones would be repaired even after gc_grace, so it was a bit more forgiving. It was never guaranteed that the inconsistency would be repaired though. I think you should have increased gc-grace or run repair within the 10 days.
See my last e-mail I wrote as a reply to my own e-mail replying Sylvain's e-mail - things get more strange now... ;-)
