Hi,

There are a couple of PRs available with this feature in the 
SchemaCompatibility class (which already exists in plain Avro/Java, but 
is now enhanced with this function). I don't know when they are slated 
to be included in master, but probably some time after 1.8.2 is release.

https://issues.apache.org/jira/browse/AVRO-2003

Best wishes,
/Anders
