Josh Elser commented on ACCUMULO-2608:
--------------------------------------

After re-reading a [blog post on Knossis|http://aphyr.com/posts/309-knossos-redis-and-linearizability],
I'm wondering if you could prune certain cycles out of the graph to reduce the "search space"
for a bug and enumerate the rest. A slightly different approach than how RW works now, but
just a thought.

> It would be useful to have the ability to replay randomwalk sequences.
> If a randomwalk fails, it is often difficult to reproduce due to the random nature of
things. If current test runs were modified to output a specially crafted module representing
their sequence, then future runs could accept it as the module to run and improve reproduction
capabilities.
