>             Project: Accumulo
>          Issue Type: Bug
>    Affects Versions: 1.4.2
>            Reporter: William Slacum
>
> The LoadFiles class gets a synchronized list of files to import and, while 
> iterating over that list, creates another list of Callable's. If the list of 
> files to load is long enough, it's possible that a bulk import on a previous 
> file in the list could finish and remove itself from the master list before 
> all of the commands to import the rest of the files are created. This causes 
> a ConcurrentModificationException when trying to fetch the next file to load.
> I think the concurrent lists support an iterator that will not fail if the 
> underlying list is modified, but if not, I think this can be solved by first 
> creating a list of Callables and then adding them to the thread pool in a 
> separate loop.
