   # [DRILL-8249](https://issues.apache.org/jira/browse/DRILL-8249): Parquet decoding error reading nation.dict.parquet from test framework.
   
   ## Description
   
   Thank you to @ArtTrush for finding and partially debugging this regression. The Parquet test file attached to the Jira issue cannot be queried with Drill 1.20.1 because it decides from column chunk metadata that a chunk does not use dictionary encoding and ignores new information found by the Parquet page reader that indicates that dictionary encoding is used. This fix restores the consideration of the `usingDictionary` flag which is updated by the page reader.
   
   ## Documentation
   N/A
   
   ## Testing
   The Drill Test Framework contains a test query and file nation.dict.parquet that reveals this bug.
