I think the idea here is that if we don't know better, we treat the
attribute as numeric.
With this change, we ignore attributes we don't know how to treat.
Is my understanding correct?

> It appears Samoa is capable of streaming a collection of files as a single
> stream effectively concatenating the files. However using Samoa
> AvroFileStream from HDFSFileStreamSource seems the stream stops at end of
