私ができるので、これは深刻な問題ですドライバーのエラーを診断したり、アプリケーションユーザーに意味のあるエラーを報告したりしないでください。私はSparkExceptionを投げる場合
、一方で、私は素敵なを取得する：
org.apache.spark.SparkException：ジョブによるステージ障害のために中止されます。タスク6 1.0は、1回失敗した段階で、最新の障害：段階1.0で失われたタスク6.0（TID 14、ローカルホスト）：org.apache.spark.SparkException：おっと
は、私は自分のアプリケーションのjarファイルを見ていないされて伝播し、例外をデシリアライズするクラスローダを推測しています（または、この場合、spark-shellで定義されたクラス）、回避策を見つけることができませんでした。何か案は？
私はアプリケーションでこれを見ているが、火花提出するが、ここで火花シェルを介して完全な例です通す：

任意のアイデア？

スパークに関連するコードがTaskResultGetter.scalaである：spark.util.Utils.getSparkClassLoader呼び出し
try {
if (serializedData != null && serializedData.limit() > 0) {
reason = serializer.get().deserialize[TaskEndReason](
serializedData, Utils.getSparkClassLoader)
}
} catch {
case cnd: ClassNotFoundException =>
// Log an error but keep going here -- the task failed, so not catastrophic
// if we can't deserialize the reason.
val loader = Utils.getContextOrSparkClassLoader
logError(
"Could not deserialize TaskEndReason: ClassNotFound with classloader " + loader)
case ex: Exception => {}
}
：スパークをロードしたクラスローダを使用している
def getSparkClassLoader: ClassLoader = getClass.getClassLoader
瓶。
--driver-class-pathまたはSPARK_CLASSPATHにアプリケーションjarを追加すると、私の問題が解決します。 –
