Just had a delightfully odd failure case where every single IT that used a minicluster would timeout and fail.
Turns out, if you happen to set a version on Accumulo (e.g. what I might do if I were testing locally and wanted to be isolated) which doesn't match what Version.java wants your version to be, an IllegalArgumentException is thrown which brings down all of the processes.
The fun part is that this Version is used no-where, save the accumulo version command. We can and should fail gracefully – there is no reason we should fail hard as we do now.
