(too much to quote) Looks to me like this should be fixable by removing hints from the node in question (I don't remember whether this is a bug that's been identified and fixed or not).
I may be wrong because I'm just basing this on a quick look at the stack trace but it seems to me there are hints on the node, for other nodes, that contain writes to a deleted column family. -- / Peter Schuller (@scode, http://worldmodscode.wordpress.com)
