---------------------------------------
Affects Version/s: (was: 1.3.7)
> Leaks a BatchScanner thread pool for each BatchDeleter

> Project: Accumulo

> Components: client

>
> Each BatchDeleter (i.e., TabletServerBatchDeleter) causes a BatchScanner thread to leak.
This is because TabletServerBatchDeleter extends TabletServerBatchReader which opens a thread
pool on construction but no close() method is offered on the BatchDeleter interface.
> Workaround: downcast BatchDeleter to either BatchScanner or TabletServerBatchDeleter,
then call close().
> It appears the close() method is available on BatchDeleter from 1.4 forward, but this
still affects 1.3 series users (which is why I'm documenting it).
> Since BatchDeleter is a one-off class - call delete() and forget - it might make sense
for it to close itself instead when complete.
