Description

Jon Hsieh pointed out that ReflectDatumWriter always returned a DatumWriter<Object>, though it's often clear (by the way the schema is constructed) that there's a more specific type that could be used. In the quote below, the second line would be preferable to the third.

  Schema schema = reflectData.getSchema(MyObject.class);
  // DatumWriter<MyObject> writer = new ReflectDatumWriter(schema);
  DatumWriter<Object> writer = new ReflectDatumWriter(schema);
