[jira] [Commented] (ARROW-14066) [C++] Possible issue with cpp StreamWriter

["Weston Pace (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-14066?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17418777#comment-17418777 ] 

Weston Pace commented on ARROW-14066:
-------------------------------------

I think the footer should be written out when the parquet::ParquetFileWriter (owned by parquet::StreamWriter) is closed.  I don't see an explicit parquet::StreamWriter::Close but the destructor of parquet::ParquetFileWriter will call close.

So, did you make sure to delete your parquet::StreamWriter instance before you tried to read the file?

> I am using the cpp streamwriter example given here: [https://github.com/apache/arrow/blob/master/cpp/examples/parquet/parquet_stream_api/stream_reader_writer.cc]
>  
> When I try to read the parquet file back in python it says: Could not open parquet input source '<Buffer>': Invalid: Parquet magic bytes not found in footer. Either the file is corrupted or this is not a parquet file
