hi @ben,

Here is the result of parquet-tools meta execution for a file that Dremio fails to open :  
[20190806-bt-KO\_DREMIO\_snappy\_parquet\_metadata.txt.zip](https://community.dremio.com/uploads/short-url/xVPTkI1HR18xZjYSUXZ7sZT1HHU.zip) (3.3 KB)

And other file generated the same day in the same way with other data that Dremio manages to open :  
[20190806-wtb-OK\_DREMIO\_snappy-parquet-metadata.txt.zip](https://community.dremio.com/uploads/short-url/a68YLSgwBGIrT7j2IGOwQivWpjJ.zip) (3.8 KB)

Those files have been written using library pyarrow version 0.13 using method write\_table of module pyarrow.parquet.  
Both of them can be read with Dremio 3.1.11

I would be happy to provide you with those files in a private way.
