      L280 looks like this:

       269 void HdfsParquetScanner::Close(RowBatch* row_batch) {
      ...
       280     for (ParquetColumnReader* col_reader : column_readers_) col_reader->Close(nullptr);
      

      Workaround

      • SET MT_DOP=0 before running COMPUTE STATS or SET MT_DOP=0 gobally
      • Refrain from setting MT_DOP!=0 manually for any query
