> Previously in the refactoring of Avro Serializer and Deserializer, a new class SerializableSchema is created for serializing the avro schema.
> [https://github.com/apache/spark/commit/96030876383822645a5b35698ee407a8d4eb76af#diff-7ca6378b3afe21467a274983522ec48eR18] 
> On second thought, we can use `toString` method for serialization. After that, parse the JSON format schema on executor. This makes the code much simpler.
