Class ExceptionFailure

java.lang.Object

org.apache.spark.ExceptionFailure

All Implemented Interfaces:

java.io.Serializable, TaskEndReason, TaskFailedReason, scala.Equals, scala.Product

public class ExceptionFailure
extends java.lang.Object
implements TaskFailedReason, scala.Product, scala.Serializable

:: DeveloperApi :: Task failed due to a runtime exception. This is the most common failure case and also captures user program exceptions.

stackTrace contains the stack trace of the exception itself. It still exists for backward compatibility. It's better to use this(e: Throwable, metrics: Option[TaskMetrics]) to create ExceptionFailure as it will handle the backward compatibility properly.

fullStackTrace is a better representation of the stack trace because it contains the whole stack trace including the exception and its causes

exception is the actual exception that caused the task to fail. It may be None in the case that the exception is not in fact serializable. If a task fails more than once (due to retries), exception is that one that caused the last failure.
