During a recent duration test run of the ruby-driver (as well as a previous
run), I see many of the following exceptions thrown in the system.log:
{noformat}

I've checked this data directory and indeed this specific db file is missing.
This would signal a database corruption.
The duration test uses a 3-node cluster. It seems like the nodes have also gone
out of sync. For example, getting a nodetool status on one node gives:
{noformat}
$ cassandra/bin/nodetool -h 10.240.61.210 status
-- Address Load Tokens Owns Host ID

While on another node it gives:
{noformat}
$ cassandra/bin/nodetool -h 10.240.210.69 status (or 10.240.185.204)
