What mapper and reducer functions were you executing?
Did you see any other exception in logs?

I'm using size/size.
No other exceptions.

The query still returns a {"size":0} document.

And how are keys composed? An example of the queried range?

Oh, I think the problem is the snapshot file saved and accessed on disk, hence 
the IOException: take a loot at the SortedSnapshot class.

If so, you should get the same exception with simple range queries too: is that 
the case?

That is very likely to be it - the range queries behave in the exact same way.

The snapshot files were indeed the problem.

Previously named <bucket>:<comparator>, which doesn't work on Win systems.
Renamed it to <bucket>-<comparator>.

Although it seems kind of obvious that it will work universally now, it should 
be verified on *nix/MacOS.

Works here on my Mac.
Good catch!
