----------------------------------
Hi Doug,
Sorry for the delay. Looks like it works, thanks!
For the record, we tried it out on an Avro file created with 1.4 (and invalid
chars in the record name):
java -jar avro-tools-1.6.0-SNAPSHOT.jar getschema ptd-sample.avro
and it successfully dumped the schema.
When we tried the same with avro-tools-1.5.1 it generated the following error:
Exception in thread "main" org.apache.avro.SchemaParseException: Illegal
character in: Cascading-Schema-0
> Support reading of files created with Avro 1.5 that use invalid characters in
> field and record names

> Project: Avro
> Issue Type: Improvement
> Affects Versions: 1.5.0, 1.5.1
> Reporter: Ken Krugler
> Assignee: Doug Cutting
> Fix For: 1.5.2

>
> Avro 1.4 had a bug that let users create schemas with invalid characters in
> field and record names.
> For example, the '-' character used to be allowed in field and record names,
> but Avro 1.5 will now fail.
> We need some kind of compatibility mode that supports schemas with invalid
> characters, so that existing files created with Avro 1.4 can be read by Avro
> 1.5.
