-------------------------------------

             Summary: Avro java library includes $ in namespace, it fails in avro cpp
                 Key: AVRO-2877
                 URL: https://issues.apache.org/jira/browse/AVRO-2877
             Project: Apache Avro
          Issue Type: Bug
          Components: java
            Reporter: Koosha Hosseiny


Hello!

This is the code from `ProtobufData.java`:

 
{code:java}
String d1 = (!outer.isEmpty() || inner.length() != 0 ? "." : "");
String d2 = (!outer.isEmpty() && inner.length() != 0 ? "$" : "");
return p + d1 + outer + d2 + inner;
{code}
 

From [here|https://github.com/apache/avro/blob/2c7b9af7d5ba35afe9cf84eae3b273a6df0612b1/lang/java/protobuf/src/main/java/org/apache/avro/protobuf/ProtobufData.java#L249]

Despite the fact that avro specification disallows $ in namespace. Hence, the output from java library can not be imported to a client using avro's cpp implementation such as BigQuery.

I'm not sure what the fix should look like?
