> It's pragmatic to package these classes in Avro, but long-term... 

Yes, you're right, it's not black and white, but pragmatic.  In the past we've generally encouraged FileSystem and InputFormat implementations to be included in Hadoop so they're easier to maintain as Hadoop's APIs evolved.  However in this case we have a new InputFormat that we'd like to be able use with older releases of Hadoop.  And we now also expect the Hadoop APIs it uses to be stable for some time.  As Hadoop's APIs stablize we might see more such user-level "library" code maintained independently from Hadoop.

Closing this as a duplicate of AVRO-493.

> HADOOP-6660 proposes adding an AvroValue wrapper for Avro data.  We should add InputFormat and OutputFormat implementations for Avro data files that use this.
