Major 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.
