Re: [jira] Commented: (HADOOP-6120) Add support for Avro types in
hadoop
Thunderbird and Mutt are at least two which does thread JIRA's threads properly.
The way they do so is by using Message-ID and In-Reply-To fields of a RFC-822
header.

I think the current Serialization interface is fine to implement 'specific' type as the schema information can be inferred from the class. The schema can't be inferred from the 'reflect' and 'generic' type classes. So the current Serialization interface doesn't seem to be sufficient to implement these. I think the Serialization interface need to be extended to pass on additional info to have implementation for 'generic' and 'reflect'.
