Christophe Le Saec commented on AVRO-3130:
------------------------------------------
Hello [~honoredb],
it does work with
{code:json}
{
"type" : "record",
"name" : "AccountEvent",
"fields" : [
{
"name" : "NullableLongArray",
"type" : [
"null",
{ "type":"array", "items":"long" }
]
}
]
}
{code}
Maybe i missed something, but i don't see the purpose of 'accountList' name
(_As it's not a field_)

> Key: AVRO-3130
> URL: https://issues.apache.org/jira/browse/AVRO-3130
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Reporter: Aaron Zinger
> Priority: Minor
>
> When a schema object is provided inside a union or as an array items type,
> the parser looks for a text value for type, doesn't find it, and throws a
> confusing error message of the form "No type: <thing with a type>".
> The error message could be fixed by having GetRequiredText distinguish
> between the key not being present and the value not being text, with the
> latter returning a message like "Value for type must be string".
> However, my preferred change would be to handle schema objects in these
> situations--it seems like it'd be compliant with the spec to have {"type":
> "string"} resolve to "string", and it would let schema generation code be a
> little simpler by letting it reuse schemas. This could also address
> https://issues.apache.org/jira/browse/AVRO-1977, I think.
> Examples below.
> {code:json}
> {
> "type": "record",
> "name": "AccountEvent",
> "fields": [
> {"type":
> ["null",
> { "name": "accountList",
> "type": {
> "type": "array",
> "items": "long"
> }
> }
> ],
> "name":"NullableLongArray"
> }
> ]
> }
> {code}
> Fails with {code:java}"No type:
> {\"name\":\"accountList\",\"type\":{\"type\":\"array\",\"items\":\"long\"}}"{code}
> The error is similar for
> {code:json}
> {
> "type": "array",
> "name": "FavoriteNumbers",
> "items": {"type":{"type": ["null","long"], "name": "NullableNumber"}}
> }
> {code}
