After pulling #181, the CockroachDB tests are all failing.

It looks like it's pulling jepsen and knossos from the network, then ignoring the jepsen jar it downloaded and using the local source (which is incompatible with the downloaded knossos). I don't think I'm setting any classpath variables or anything that would cause it to look there (although there are a lot of layers in the scripts here and I don't know what variables to look for). Any idea what I might be doing wrong? Should I just bump the jepsen version in cockroachdb/project.clj to 0.1.6-SNAPSHOT?

So the competition checker was introduced in Knossos 0.3.0, and is referred to by Jepsen 0.1.6-SNAPSHOT. Cockroach refers to 0.1.5, which means it shoooouldn't point to the competition checker. Possible answers:

Yep, I have this checkouts directory. Sounds like I should just remove that.
