It's slow going finding the time to do so but I'm working on that. We do have another table that has one or sometimes two columns per row. We can run jobs on it without issue. I looked through org.apache.cassandra.hadoop code and don't see anything that's really changed since 1.1.5 (which was also using thrift-0.7) so something of a puzzler about what's going on.
