Subject [jira] [Created] (AVRO-1473) Nested schema reference with empty namespace cannot be parsed
Date Sun, 02 Mar 2014 23:06:20 GMT
Gabriel Reid created AVRO-1473:
----------------------------------

             Summary: Nested schema reference with empty namespace cannot be parsed
                 Key: AVRO-1473
                 URL: https://issues.apache.org/jira/browse/AVRO-1473
             Project: Avro
          Issue Type: Bug
          Components: java
            Reporter: Gabriel Reid


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.
