[jira] Commented: (HADOOP-6120) Add support for Avro types in hadoop

    [ https://issues.apache.org/jira/browse/HADOOP-6120?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12725490#action_12725490 ] 

Sharad Agarwal commented on HADOOP-6120:
----------------------------------------

The Serialization interface can be implemented for Avro types. Currently Avro has 3 types in java: specific, reflect and generic. 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'.

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.
