スタンドアロンマシンでSparkを使用して簡単なHello Worldプログラムを実行できます。しかし、Spark Contextを使って単語カウントプログラムを実行し、pysparkを使用してそれを実行すると、次のエラーが発生します。 ERROR SparkContext：SparkContextの初期化中にエラーが発生しました。 java.io.FileNotFoundException：ファイル・ファイルの追加：/Users/tanyagupta/Documents/Internship/Zyudly%20Labs/Tanya-Programs/word_count.pyが存在しません。 私はMac OS Xを使用しています。私はbrewを使ってsparkをbrew install apache-sparkでインストールしました。どんなアイデアが今何がうまくいかないの？スパークのデフォルトのlog4jのプロファイルを使用してApache Spark- SparkContextの初期化中にエラーが発生しました。 java.io.FileNotFoundException
