> Similar to SequenceFiles are Apache Avro's DataFiles. Since these are getting
> popular as a data format, perhaps it would be useful if {{fs -text}} were to
> add some support for reading it, like it reads SequenceFiles. Should be easy
> since Avro is already a dependency and provides the required classes.
> Of discussion is the output we ought to emit. Avro DataFiles aren't simple as
> text, nor have they the singular Key-Value pair structure of SequenceFiles.
> They usually contain a set of fields defined as a record, and the usual text
> emit, as available from avro-tools via
> http://avro.apache.org/docs/current/api/java/org/apache/avro/tool/DataFileReadTool.html,
> is in proper JSON format.
> I think we should use the JSON format as the output, rather than a delimited
> form, for there are many complex structures in Avro and JSON is the easiest
> and least-work-to-do way to display it (Avro supports json dumping by itself).
