Doug Cutting commented on AVRO-875:
-----------------------------------
This is equivalent to parse(url.openStream()), no?
A URL is generally less available than a File. Most applications that used URLs for Schemas would probably require more than this, since they'd probably want to cache the content, perhaps to a file, so they could continue to operate when the URL's content is not available on the network. So I wonder if this method will be that useful on its own.
Do you have a use case where this API would be convenient? Can you please describe it a bit? Thanks!

Bill Graham commented on AVRO-875:
----------------------------------
The use case I have in mind is of an internal repository that would me more available than fetching Schema over the public internet. We might have multiple producers of a given data type (Pig MR jobs, Java standalone writers, etc.). Being able to pull files from a URL would be convenient even if only utilized in development.
Yes, we could just use url.openStream() though, which slipped my mind. For that reason I think we can just close this JIRA out if you agree.
