John Vines commented on ACCUMULO-3918:
--------------------------------------

I mean, ultimately it's just a reseek with a new column family filter, I would think...

> 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.
