Same question as Steven. What is the impact. It seemed from the bug the impact is both wrong results and partition pruning not working. Drill is a generally available project now and there are users who created millions of parquet files using previous version of Drill. Hence I think is a release blocker unless there is a clean path and proper testing on how the users migrate to new versions.
