Spark com.databricks.spark.csvはノードスナッピーを使用してスナップ圧縮ファイルを読み込むことができません

Question

私は、スナッピー圧縮アルゴリズム（node-snappyパッケージを使用）を使用して圧縮されたS3上のcsvファイルをいくつか持っています。私はcom.databricks.spark.csvを使用してスパークでそれらのファイルを処理したいのですが、一貫して無効なファイル入力エラーが発生しています。

コード：

file_df = sqlContext.read.format('com.databricks.spark.csv').options(header='true', inferschema='true', codec='snappy', mode='FAILFAST').load('s3://sample.csv.snappy') 

エラーメッセージ： - 基本的にPythonのスナッピーはのHadoopてきぱきと互換性がない
