@gardellajuanpablo I think for this case we should avoid making any changes
to RecordField or DataTypeUtils at all. This is an oddity of Avro specifically.
I do think that it makes sense to honor the way that Avro deals with this case,
but I think this should be done purely by addressing the issue in AvroTypeUtil.
I think we can just update the AvroTypeUtil#createSchema(Schema, String,
SchemaIdentifier) with something like this:
```
Object defaultValue = field.defaultVal();
if (fieldSchema.getType() == Schema.Type.ARRAY &&
!DataTypeUtils.isArrayTypeCompatible(defaultValue)) {
defaultValue = new Object[0];
}
recordFields.add(new RecordField(fieldName, dataType,
defaultValue, field.aliases(), nullable));
```
And I think that will address the issue without breaking anything else.
Thoughts?
