[jira] [Created] (DRILL-7864) Parquet file could not be read correctly

Matthias Rosenthaler created DRILL-7864:
-------------------------------------------

             Summary: Parquet file could not be read correctly
                 Key: DRILL-7864
                 URL: https://issues.apache.org/jira/browse/DRILL-7864
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Parquet
    Affects Versions: 1.18.0
            Reporter: Matthias Rosenthaler
         Attachments: output.parquet

The following parquet file which is generated by ParquetSharp (which is using the underlying apache arrow c++ lib) is not readable by drill. The values of the columns are displaced. If I write the affected float32 columns "InjectionRate" and "I_injection_IA" as float64, everything is fine.

Also created a ticket for the arrow project, but they redirect me to the drill project. https://issues.apache.org/jira/browse/ARROW-11629
