[jira] [Commented] (AVRO-1476) Make position field of org.apache.avro.Schema not transient.

    [ https://issues.apache.org/jira/browse/AVRO-1476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13999249#comment-13999249 ] 

Sandy Ryza commented on AVRO-1476:
----------------------------------

+1 to this as well.  Kryo serialization, the most common internal serialization framework for Spark also ignores this field, making it impossible to pass GenericData.Records through Spark stages.

> [~kryzthov] did some research into possible causes/reasons for this field to be marked as transient but was unable to find any reason. The org.apache.avro.Schema class is not marked as serializable so this transient field serves no purpose. This transient field can cause odd behaviors with external serialization frameworks (and the built-in java serialization framework) when trying to serialize schemas.
