Philipp, I would say that it is a bug. I ran into the same problem some time ago. Essentially, AvroStorage does not recognize globs and does not recognize commas, both of which are supported by hadoop's FileInputFormat. I ended up patching AvroStorage to make it compatible with hadoop's semantics of input paths. I haven't submitted a patch though. If there is some interest, I'd be more than glad to submit it.
