Subject [jira] [Updated] (AVRO-1362) Avro schema array cannot reference previously defined record types
Date Thu, 15 Aug 2013 19:12:49 GMT

     [ https://issues.apache.org/jira/browse/AVRO-1362?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bill Baird updated AVRO-1362:
-----------------------------

    Description: 
The following schema compiles successfully in Avro(c#), but in Avro(Java)returns a "Type not
supported: Invoice" when parsing the "ListOfInvoices" array.  
Problem appears to be in the parse method.  {"items": "Invoice"} does not properly parse to
find the "Invoice" type.

{   "namespace": "SampleClasses",
    "name": "Batch",
    "type": "record",
    "fields": [
		{ "name": "Invoices", "type": {
				"type": "array",
				"items": {
                            "name": "Invoice",
                            "type": "record",
                            "fields": [
                                { "name": "Id", "type": "string" }
                            ]
						}
				}
		},
		{ "name": "SingleInvoice", "type": "Invoice" },            // This reference to "Invoice"
works fine.
		{ "name": "ListOfInvoices", "type": {
				"type": "array", "items": {	"type": "Invoice" }    // Fails - does not get previous definition
of "Invoice"
			    }
		}
	]
}
