Keith Turner commented on ACCUMULO-1280:
----------------------------------------
We have found with [PR#159|https://github.com/apache/accumulo/pull/159] that
trying to add {{close()}} to iterators has many sharp edges for us and users.
Another approach to solve this problem is to add a
{{addCleanupAction(Runnable)}} method to {{IteratorEnvironment}}. This allows
the iterator to add clean up actions that will be called when Accumulo is
finished with the iterator.

> It would be useful if Accumulo iterators had a close method. Accumulo would
> call this when its finished using the iterator stack.
> How would this work w/ isolation?
> Is it ok to break the iterator API?
