> A change made in NodeImpl.cc under AVRO-1026 has introduced a bug that
> corrupts JSON schemas when writing them to disk or dumping to a stream. This
> manifested when using DataFileWriter to generate a data file, and the schema
> stored in the header was corrupted from the original schema provided.
>
> e.g
>
> This:
> {noformat}
> {
> “type”: “fixed”,
> “name”: “Unsigned16”,
> “size”: 2
> }
> {noformat}
>
> Becomes this:
> {noformat}
> {
> “type”: “fixed”,
> “size”: 2,
> “name” : “Unsigned16”,
> }
> {noformat}
> Note the extraneous comma after the ‘name’ attribute.
> The bug exists for Avro 'fixed' types, and has not been observed for other
> types. A test case will be developed.
> The bug can be fixed by simply re-ordering the code in NodeFixed::printJson.
