Berenguer Blasi commented on CASSANDRA-16546:
---------------------------------------------
Difficult to repro either locally and won't repro on the multiplexer. I manged
to do it on a slow virtual env and only seldom yet.
The problem was that the test class expects to be ran as a tool with a stable
env under it's feet. On a test class there are other async things happening
such as test method cleanup logic. We can see the failure was the tool being
ran for a specific ks.cf but complaining on a different one i.e.

This came from the tool loading schema on startup from disk

The proposed solution is to force drop tables in-between such tests and it
doesn't repro anymore.
