class Accumulable[R, T] extends Serializable

A datatype that can be accumulated, i.
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.
trait AccumulatorParam[T] extends AccumulableParam[T, T]

A simpler version of AccumulableParam where the only datatype you can add in is the same type as the accumulated value.
case class Aggregator[K, V, C](createCombiner: (V) ⇒ C, mergeValue: (C, V) ⇒ C, mergeCombiners: (C, C) ⇒ C) extends Product with Serializable

A set of functions used to aggregate data.
abstract class Dependency[T] extends Serializable

Base class for dependencies.
class DoubleRDDFunctions extends Logging with Serializable

Extra functions available on RDDs of Doubles through an implicit conversion.
class HashPartitioner extends Partitioner

A Partitioner that implements hash-based partitioning using Java's Object.hashCode.
class JavaSerializer extends Serializer

A Spark serializer that uses Java's built-in serialization.
trait KryoRegistrator extends AnyRef

Interface implemented by clients to register their classes with Kryo when using Kryo serialization.
class KryoSerializer extends Serializer with Logging

A Spark serializer that uses the Kryo 1.x library.
trait Logging extends AnyRef

Utility trait for classes that want to log data.
abstract class NarrowDependency[T] extends Dependency[T]

Base class for dependencies where each partition of the parent RDD is used by at most one partition of the child RDD.
class OneToOneDependency[T] extends NarrowDependency[T]

Represents a one-to-one dependency between partitions of the parent and child RDDs.
class OrderedRDDFunctions[K, V] extends Logging with Serializable

Extra functions available on RDDs of (key, value) pairs where the key is sortable through an implicit conversion.

Extra functions available on RDDs of (key, value) pairs through an implicit conversion.
trait Partition extends Serializable

A partition of an RDD.
abstract class Partitioner extends Serializable
