------------------------------------
For the record, the ability to separately annotate the field and its schema is
documented at:
http://avro.apache.org/docs/current/idl.html#minutiae_annotations
> IDL Tool - Field properties are added against schema instead of field
> ---------------------------------------------------------------------
>
> Key: AVRO-1168
> URL: https://issues.apache.org/jira/browse/AVRO-1168
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.7.1
> Reporter: Cristian Opris
> Priority: Minor
>
> In Idl.jj, field properties are added against the field *schema* instead of
> the field, resulting in an error if different fields of the same *record*
> type are annotated with the same property name.
> Example:
> <code>
> record RecordA {
> }
> record RecordB {
> @Prop("")
> RecordA a1
> @Prop("")
> RecordA a2
> }
> </code>
> Note this fails even if a1 and a2 are in different records (since the Schema
> instance is shared)
> Proposed fix: - change Idl.jj to add props agains the fields props, not the
> schema:
> <code>
> for (String key : props.keySet())
> type.addProp(key, getTextProp(key, props, token));
> </code>
> should read:
> <code>
> field.addProp(...)
> </code>
