sijie opened a new issue #4840: Pulsar schema admin API doesn't support uploading key/value schema
URL: https://github.com/apache/pulsar/issues/4840
 
 
   **Describe the bug**
   
   Currently Pulsar schema api converts schema data (bytes) to string and uploads the string to Pulsar admin endpoint. It works for struct schemas and primitive schemas. Primitive schemas doesn't contain any schema data and struct schemas store UTF_8 encoded data. 
   
   However it doesn't work for key/value schema because it will contain illegal bytes in schema data.
   
   **To Reproduce**
   
   ```
   Schema<KeyValue<User, User>> schema = Schema.KeyValue(
       Schema.AVRO(User.class),
       Schema.AVRO(User.class)
   );
   
   admin.schema().createSchema(topic, schema.getSchemaInfo());
   ```
   
   **Expected behavior**
   
   Admin api should be able to upload key/value schema.
