Schema for Array of Array in Avro

[#1]

Greetings!

I was trying to write some sample Avro schemas, and was unable to create one for an array of array.

Sample json -

{
  "testarray":[[1,2,3][4,5,6] ... ]
}		

My best try to create the schema -

{
  "name": "testarray",
  "type": {
    "type":"array",
    "items": {
      "type": {
        "type":"array",
        "items": {
          "name": "temp",
          "type":"long"
        }
      }
    }
  }
}

But the schema parser throws this error -

---

Exception in thread "main" org.apache.avro.SchemaParseException: No type: {"name":"testarray","type":{"type":"array","items":{"type":{"type":"array","items":{"name":"temp","type":"long"}}}}}

Is there something wrong with the schema I've written, or is this not supported in Avro?

Any help would be much appreciated.

Try this format:

{

"name": "testarray"
"type": "array", 
"items": {
	"name": "Record1Array”, 
	"type": "record", 
	"fields" : [{
		“name": "Array1Value”, 
		"type": {
			"type": "array", 
			"items": {
				"name": "Record2Array”,
				"type":"record", 
				"fields" : [{
						"name”:”Array2Value”, 
						"type": "string"
					   }]
				  }
			}
		  }]
	}
}

Also, when dealing with Avro use Avro IDL; It makes writing/testing schemas easier.

This schema corresponds to an array of records (which in turn has arrays), but not an array of array?
