@alexeykudinkin Could you please review it? Really thanks! Geng Xiaoyu and me have fix comments in RFC46. I found `@DefaultSerializer(HoodieSparkRecordSerializer.class)` and user need not to set spark.kryo.registrator.

> @wzx140 can you please validate that `@DefaultSerializer(HoodieSparkRecordSerializer.class)` leads to `HoodieSparkRecordSerializer` being used by Kryo when shuffling? Yes. I check it in UT with printing some message in HoodieSparkRecordSerializer.
