Gabriel Reid updated AVRO-1473:
-------------------------------

    Attachment: AVRO-1473.patch

Patch to resolve this issue. The approach taken is to attempt to retrieve the name with the enclosing record's namespace, and if that fails, the name lookup is attempted with the empty namespace.

> Related to AVRO-1295, a reference to a nested named schema with an empty namespace cannot be parsed. An example of such a schema is as follows:
> {code}
> {
>   "type" : "record",
>   "name" : "Outer",
>   "namespace" : "space",
>   "fields" : [ {
>     "name" : "f1",
>     "type" : {
>       "type" : "record",
>       "name" : "Inner",
>       "namespace" : "",
>       "fields" : [ ]
>     }
>   }, {
>     "name" : "f2",
>     "type" : "Inner"
>   } ]
> }
> {code}
> Attempting to parse this results in the following exception:
> org.apache.avro.SchemaParseException: "Inner" is not a defined name. The type of the "f2" field must be a defined name or a \{"type": ...\} expression.
> The issue seems to be that the lookup for the name "Inner" is done with the namspace of the encoding record, and not with the empty namespace for this case.
