Subject [jira] Created: (AVRO-529) Cannot use array type in avro request
Date Wed, 28 Apr 2010 00:07:31 GMT
Cannot use array type in avro request
-------------------------------------

                 Key: AVRO-529
                 URL: https://issues.apache.org/jira/browse/AVRO-529
             Project: Avro
          Issue Type: Bug
          Components: ruby
    Affects Versions: 1.4.0
         Environment: Mac OS X
            Reporter: Wanli Yang


While it is OK to use array in avro response, we get the following error when using it in
the type definition. e.g.:

  {
    "namespace": "my_namespace",
    "protocol": "MyProtocol",
    "types": [
      {
        "name": "Thing", "type": "record", "fields": [
          { "name": "id", "type": "long" },
          { "name": "other_ids", "type": "array", "items": "long" }
...
