Keith Turner commented on ACCUMULO-1321:
----------------------------------------
[~vines] I took a quick look at the patch. Maybe the unit test should call the
new generateVFS function. Also, need to add some unit test that use a jar
where the class differs. I kinda have some of the unit test stuff done. If
you check this patch in I can work on the unit test.

> We have a table setup that uses some custom iterators. We ran an MR job
> against it without issues. We then ran the job immediately after the first
> one wrapped and 2 of my tservers errored with ClassNotFoundException, even
> though it ran just fine before.
> Unfortunately we don't have a stack trace (to see if it was breaking
> differently in the VFSClassLoader), nor a convenient way to recreate
> currently. We're working on reproducing it in order to get more information.
