   Followed @Jefffrey  clue and finally this problem was solved.
   when file name end with "csv.bz2", should set option with .file_extension("csv.bz2").
   
   ```
       let csv_options = CsvReadOptions::default()
           .has_header(true)
           .file_compression_type(FileCompressionType::BZIP2)
           .file_extension("csv.bz2");
       let df = ctx
           .read_csv(&format!("{testdata}/csv/summary.csv.bz2"), csv_options)
           .await?;
       let df = df
           .filter(col("status").eq(lit("OK")))?
           .select_columns(&["name", "id"])?;
   
       df.show().await?;
   ```
