Type Members

class Accumulable[R, T] extends Serializable

A data type that can be accumulated, ie has an commutative and associative "add" operation, but where the result type, R, may be different from the element type being added, T.
trait AccumulableParam[R, T] extends Serializable

Helper object defining how to accumulate values of a particular type.
class Accumulator[T] extends Accumulable[T, T]

A simpler value of Accumulable where the result type being accumulated is the same as the types of elements being merged, i.
trait AccumulatorParam[T] extends AccumulableParam[T, T]

A simpler version of org.apache.spark.AccumulableParam where the only data type you can add in is the same type as the accumulated value.

Value Members

object ExecutorLostFailure extends TaskFailedReason with Product with Serializable

:: DeveloperApi :: The task failed because the executor that it was running on was lost.
object Partitioner extends Serializable
object Resubmitted extends TaskFailedReason with Product with Serializable

:: DeveloperApi :: A org.apache.spark.scheduler.ShuffleMapTask that completed successfully earlier, but we lost the executor before the stage completed.

object UnknownReason extends TaskFailedReason with Product with Serializable

:: DeveloperApi :: We don't know why the task ended -- for example, because of a ClassNotFound exception when deserializing the task result.
