John Vines commented on ACCUMULO-1321:
--------------------------------------

That makes me worry about memory use and the cruft is a bigger concern to
me for long running instances.

Sent from my phone, please pardon the typos and brevity.

> 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.
