I have a very similar issue myself and would love to know what (if anything) needs to be done (I'm using 1.1.6 at the moment). After stress-test (maximum load), I had the following on my nodes (every IP is changed to the corresponding fake number): This already shows uneven load despite the fact that nodes actually hold the same amount of data (according to effective-ownership and application design / token values). However I then proceeded to drop the single keyspace that was on this cluster and I got this: Why 11.111.111.1 still has 700+ MB of data? I tried nodetool repair, nodetool cleanup, and node restart (for 11.111.111.1) -- none of that helped (it still had those 700+ MB of data). Here's info from the filesystem on that node: And here is syslog from Cassandra when I restarted 11.111.111.1 node: I'd much appreciate if someone can provide some insight as to what is going on and what (if anything) needs to be done.
