Description
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:
{ "type" : "record", "name" : "Outer", "namespace" : "space", "fields" : [ { "name" : "f1", "type" : { "type" : "record", "name" : "Inner", "namespace" : "", "fields" : [ ] } }, { "name" : "f2", "type" : "Inner" } ] }
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.
