Keith Turner commented on ACCUMULO-2608:
----------------------------------------
As I have watched random walk graphs grow over time I have realized two things.
First, increasing the graphs size may increase the possible number of bugs
that can be found. Second, this may come at the cost of taking longer to find
any particular bug.
I suspect for many bugs that random walk finds there is a cyclic sub-graph that
will reproduce a particular bug much more quickly. However its probably not
feasible to automatically find this subgraph. If this sub-graph could be
found through automated trial and error, it would make it easier for the
developer to reproduce the bug.

> 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.
