There has not, and it is not slated for 1.5.
Do you have thoughts on what you would like to see?

> Project: Accumulo
> Issue Type: Improvement
> Components: tserver
> Reporter: Eric Newton
> Assignee: Keith Turner
>
> Presently, the iterator stack can be created and destroyed at the whim of the
> tserver and its buffering needs. In complex iterations, lower-level
> iterators can make significant progress which is not inherently obvious in
> any returned key. When the iterator stack is re-created to continue a query,
> the last key returned is used to {{seek()}} the iterators. Lower-level
> iterators must re-scan their data to move back to the old position.
> Consider a mechanism to save progress beyond the last key returned.
