I came across the exact same problem on Ubuntu 14.04 and I was able to solve it by removing /var/lib/cassandra completely, as user2278196 suggested in the comments of his original question.

Mind you: I did this on a reasonably clean system, so I was completely sure I wouldn't loose any information.

I don't think you could do this on a machine that has actual data without losing it. Be careful!

I'll expand a little on what @aurand is saying, here is how to upgrade Cassandra from 0.x or 1.1.x to 2.x.

First upgrade to 1.2.9 apt-get install cassandra=1.2.9.

Then run nodetool upgradesstables (you have to otherwise some unexpected things will happen) , follow this process with nodetool compactionstats (or even better watch -n 2 nodetool compactionstats) it may take days depending on your data.

Finally upgrade to the latest version apt-get install cassandra and run nodetool upgradesstables again. Then you're done.

Note: instead of nodetool upgradesstables you may use nodetool scrub but it seems to be recommended to use upgradesstables instead.
