Note streams can be very long running, so this isn't about some short 
window.  It could even be that I'm moving to a different bucket (but don't want 
to loose my exactly once guarantees of a very long running stream).

I agree the documentation should be explicit about the expectations of the 
filename for this parameter.

I know that's the *current* use case, but I'm thinking about future 
confusion, especially as the use case you espoused, "move from s3n to s3a 
within the same window" isn't likely to be that common in a running app, is it?
At the very least, the documentation needs to be explicit about what works 
and what doesn't here.

The use case here is when you have truly unique filenames (i.e. they 
contain a guid).  This is actually pretty common in my experience.  We 
definitely shouldn't turn this on by default, but as implemented I think the 
semantics are pretty clear and this option is useful.

-1, non binding

I understand the rationale for this, to aid migration from s3/s3n to s3a, 
but given the need is schema independence, you should be using the full path 
name from `Path.getUri().getPath()` instead of getName(), which means only the 
filename is checked.

match only on name and the two files
```
s3a://bucket/incoming/dataset.avro
s3a://bucket/2015/12/dataset.avro
```
will be mistaken for the same file, even when they aren't. If this scenario 
arises then someone will end up fielding support calls about missing data, or 
worse, incorrect query results.

If you use the full path, that problem goes away and the filtering is only 
on schema and filesystem/bucket name.
