pysparkストリーミングチェックポイントから復元

Question

有効なチェックポイントでpysparkストリーミングを使用します。 最初の打ち上げは成功したが時にエラーで再起動がクラッシュ：それは私のミスで申し訳ありませんが、スパークコンテキストaddPyFileによって追加

。あなたがssc.addPyFileを設定するのです

if __name__ == '__main__': 
    ssc = StreamingContext.getOrCreate('', None) 
    ssc.sparkContext.addPyFile() 

    ssc.start() 
    ssc.awaitTermination()
