Do you know if there are any plans to have it fixed? If yes, is there any planned release date
for it?

Thank you in advance

    Subject: Querying Parquet files in 2.0 format
    
    Hi everyone,
    
    I am trying to query Parquet files written in the 2.0 format but I am getting the following
error:
    org.apache.drill.common.exceptions.UserRemoteException: DATA_READ ERROR: Exception occurred
while reading from disk. File: /performance/ParquetFooData2.parquet Column: constantString
Row Group Start: 15780070 File: /performance/ParquetFooData2.parquet Column: constantString
Row Group Start: 15780070 Fragment 0:0 [Error Id: f41d39a1-6983-47f4-9834-3068017a28bd on
drill_1:31010]
    
    However, if I just change the code which is generating the Parquet file to write it in
1.0 format it works like a charm. Does Drill understands Parquet files in 2.0 version? Or
am I doing something wrong?
    
    Best regards,
    Oscar
