Yeah, like I hinted at above, this was a quick hack to get this
functionality and I hope to remove it (despite being a very nice library to
use). Ideally, I'd not need any extra dependencies to do it (currently don't
have any deps outside of accumulo-core, junit and slf4j that I recall), and I'd
prefer to leave it that way. If it's hard to do with regular reflection libs,
Guava sounds like a nice choice. Thanks for the recommendation.
> create an iterator fuzz tester

> Project: Accumulo
> Issue Type: New Feature
> Components: test
> Reporter: Eric Newton
> Assignee: Josh Elser
>
> Users often write iterators without fully understanding its limits and
> lifetime. Accumulo should have an iterator fuzz-tester which will take user
> data and run the iterator under extreme conditions. For example, it should
> re-create and re-seek the iterator with every key returned. It could
> automatically compare results of such a run with the naive run, which seeks
> to the beginning and scans all the data.
