> If an exception is thrown while serializing a record in
> DataFileWriter<D>.append(D) partial contents of that serialization will end
> up in the file. This corrupts the block.
> DataFileWriter should ensure that the buffer is rewound to the state prior to
> the record write in the case of an exception thrown during serialization to
> prevent creating a corrupt file.
