----------------------------------------

             Summary: Transient error - VARDECIMAL(40, 6) exceeds maximum suppored precision of 38 
                 Key: DRILL-7960
                 URL: https://issues.apache.org/jira/browse/DRILL-7960
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.20.0
         Environment: Drill in Docker

Parquet Files with VARDECIMAL(29,6)

 
            Reporter: Nick Stenroos-Dam


We are using a lot of decimals in our data and keep running into issues.

The latest issue is this error message:
{code:java}
SYSTEM ERROR: Drill Remote Exception

Please, refer to logs for more information.

 The strange thing is, that if we restart Drill without modifying the datasource or query, the error goes away.

I haven't been able to create a minimal reproduction example yet. :'(
