[jira] [Created] (ARROW-11629) Write float32 make parquet files not readable for some tools

Matthias Rosenthaler created ARROW-11629:
--------------------------------------------

             Summary: Write float32 make parquet files not readable for some tools
                 Key: ARROW-11629
                 URL: https://issues.apache.org/jira/browse/ARROW-11629
             Project: Apache Arrow
          Issue Type: Bug
    Affects Versions: 3.0.0
            Reporter: Matthias Rosenthaler
         Attachments: output.csv, output.parquet

If I try to read the following csv file with pyarrow, changing the float64 columns to float32 and export it to parquet, the parquet file gets corrupted. It is not readable for apache drill or Parquet.Net any longer.
