Hi All, We are running Cassandra 2.0.2 and have recently stumbled upon an issue with nodetool repair. Upon running nodetool repair on each of the 5 nodes in the ring (one at a time) we observe the following exceptions returned to standard out;

There also does not appear to be any additional info in /var/log/cassandra/cassandra.log. We have tried restoring a recent snapshot of the keyespace in question to a separate staging ring and the repair runs successfully and without exception there. This is even after we tried insert/delete on the keyspace in the separate staging ring. Has anyone seen this behavior before and what can we do to resolve this? Any assistance would be greatly appreciated. Best regards, -Dave
