>             Project: Accumulo
>          Issue Type: Improvement

>    Affects Versions: 1.6.0

>
> While looking through the compactor code, I noticed that we load the iterator 
> stack for each locality group written and drop it when we're done. This means 
> if a user reconfigures iterators while a locality group is being written, the 
> following locality groups will be compacted inconsistently with the rest of 
> the file.
> We should really read the stack once and be consistent for the entire file 
> written.
