> Currently, RecordWriter#clearBuffers is only used to finish the current BufferBuilder and it does not clear buffers any more. Previously, it was used to recycle the partially filled buffer in the serializer but currently the serializer does not contains any network buffer any more.
> For now, only some tests and DataSet classes use it and all of these usage should be replaced by RecordWriter#close which dose the same thing. Besides, for FLINK-19297, we do not want to keep this method in the new ResultPartitionWriter Interface. So in this ticket, we propose to remove clearBuffers from the public interfaces of RecordWriter.
