Description

I am working on converting xsd to avro schema
 
XSD snippet:

 
<xsd:element name="roleNotesGroup"><xsd:complexType><xsd:sequence><xsd:element name="roleNotesSubGroup" minOccurs="0" maxOccurs="unbounded"><xsd:complexType><xsd:sequence><xsd:element name="roleNotesGroup" minOccurs="0" maxOccurs="unbounded"><xsd:complexType><xsd:sequence><xsd:element name="roleNotes" type="xsd:string" minOccurs="0"><xsd:annotation><xsd:appinfo><source application="CUSTOMER" field="REL.CUSTOMER"/><fieldPiiAttribute value="INDIRECT"/><fieldPiiPurpose value="LEGITIMATE"/><fieldPiiEraseOption value="NO.ACTION"/><fieldPiiAccessibility value="ACCESS PORTABLE"/></xsd:appinfo></xsd:annotation></xsd:element></xsd:sequence><xsd:attribute name="index" type="xsd:integer"/></xsd:complexType></xsd:element></xsd:sequence><xsd:attribute name="index" type="xsd:integer"/></xsd:complexType></xsd:element></xsd:sequence><xsd:attribute name="index" type="xsd:integer"/></xsd:complexType></xsd:element>

I am using
Schema schema = Schema.createRecord(name, null, null, false);
to create a avro schema record. In the above xsd roleNotesGroup is a child of roleNotesSubGroup which is a child of roleNotesGroup. I can recursively obtain the avro schema till roleNotesSubGroup which is then converted to list.

 
List<Schema.Field> is obtained recursively.

Now the problem is when i try to add the Fields formed to the head element roleNotesGroup using

 
Schema schema = Schema.createRecord(name, null, null, false);

schema.setFields(schemaFields);

I get the following error : SchemaParseException: can't redefine roleNotesGroup

 

Is there any restriction in avro or avro conversion that the same names should not occur again?
