> As I understand it, the class {{BlockMetaData}} has a {{getTotalByteSize}} and a {{getCompressedSize}}.  However, in the case of {{ParquetFileWriter}}, there is one place where the compressed size is being written into {{totalByteSize}} instead of the uncompressed size.  This looks incorrect.
> {code:java|title=ParquetFileWriter}
> private BlockMetaData currentBlock;
> ...
> public void appendRowGroup(SeekableInputStream from, BlockMetaData rowGroup,
>     boolean dropColumns) throws IOException {
>     ...
>     currentBlock.setTotalByteSize(blockCompressedSize);
> }
> {code}
