Type Members

1. class Accumulable[R, T] extends Serializable

   A datatype that can be accumulated, i.

2. trait AccumulableParam[R, T] extends Serializable

   Helper object defining how to accumulate values of a particular type.

3. 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.

4. 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.

5. case class Aggregator[K, V, C](createCombiner: (V) ⇒ C, mergeValue: (C, V) ⇒ C, mergeCombiners: (C, C) ⇒ C, mapSideCombine: Boolean) extends Product with Serializable

   A set of functions used to aggregate data.

6. abstract class Dependency[T] extends Serializable

   Base class for dependencies.

7. class DoubleRDDFunctions extends Logging with Serializable

   Extra functions available on RDDs of Doubles through an implicit conversion.

8. class HashPartitioner extends Partitioner

   A Partitioner that implements hash-based partitioning using Java's Object.hashCode.

9. class JavaSerializer extends Serializer

   A Spark serializer that uses Java's built-in serialization.

10. trait KryoRegistrator extends AnyRef

    Interface implemented by clients to register their classes with Kryo when using Kryo serialization.

11. class KryoSerializer extends Serializer with Logging

    A Spark serializer that uses the Kryo 1.x library.

12. trait Logging extends AnyRef

    Utility trait for classes that want to log data.

13. 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.

14. class OneToOneDependency[T] extends NarrowDependency[T]

    Represents a one-to-one dependency between partitions of the parent and child RDDs.

15. class OrderedRDDFunctions[K, V] extends Logging with Serializable
