Robert Chu commented on AVRO-1476:
----------------------------------
I would think you would want to serialize this field. Without serializing it,
the position of each field in a record would be lost. Unless I'm misreading
this, not having correct position information for a field in a record would
cause all fields to be written to a single position. Since transient fields
will get reset to their type's default value, to support regenerating this
field post-serialization, either the marker value for "uninitialized value"
should be changed to 0 (the default value for int) or the need to regenerate
this cached variable should be indicated elsewhere.
> Make position field of org.apache.avro.Schema not transient.

> Project: Avro
> Issue Type: Task
> Components: java
> Affects Versions: 1.8.0, 1.7.7
> Reporter: Robert Chu
> Priority: Minor
> Attachments: AVRO-1476.patch

> [~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.
