title: Generate Avro Schema from certain Java Object
body: <p>Apache Avro provides a compact, fast, binary data format, rich data structure for serialization. However, it requires user to define a schema (in JSON) for object which need to be serialized. </p>
  
  <p>In some case, this can not be possible (e.g: the class of that Java object has some members whose types are external java classes in external libraries). Hence, I wonder there is a tool can get the information from object's .class file and generate the Avro schema for that object (like Gson use object's .class information to convert certain object to JSON string).</p>
