17. def pullFromPath[T](cacheFiles: Seq[Path], path: Path, configuration: Configuration = new Configuration, memoise: Boolean = false)(f: (FSDataInputStream) ⇒ T): Option[T]

    

18. def pullObject[T](cacheFiles: Array[Path], path: Path): Option[T]

    

    pull an object from the cache by passing the cache paths directly

19. def pullObject[T](configuration: Configuration, tag: String, memoise: Boolean = false): Option[T]

    

    Get an object that has been distributed so as to be available for tasks in the current job.

20. def pullObjectDeserialise[T](configuration: Configuration, tag: String, deserialiser: (DataInputStream) ⇒ T, memoise: Boolean = false): Option[T]

    

    Get an object that has been distributed so as to be available for tasks in the current job.

21. def pullPath[T](configuration: Configuration, path: Path, memoise: Boolean = false)(f: (FSDataInputStream) ⇒ T): Option[T]

    

    Pulling an object from a given path.

    Pulling an object from a given path.

    We first try paths from:

    • the local cache then
    • the distributed cache then
    • the passed path itself (this is useful if we are on the client)

    Once a FSDataInputStream is successfully opened, the function f can do its job to recreate the object:

    • use the Serialiser to deserialise the object
    • use a WireFormat to deserialise the object

22. def pushObject[T](configuration: Configuration, obj: T, tag: String, check: Boolean = true): Path

    

    Distribute an object to be available for tasks in the current job using xstream

    Distribute an object to be available for tasks in the current job using xstream

    By default check right away if the object can be deserialised

23. def pushObject[T](configuration: Configuration, obj: T, serialiser: (T, DataOutputStream) ⇒ Unit, tag: String): Path

    

    Distribute an object to be available for tasks in the current job

24. final def synchronized[T0](arg0: ⇒ T0): T0

    

    Definition Classes

    AnyRef

25. def tagToPath(configuration: Configuration, tag: String): Path

    

    Make a local filesystem path based on a 'tag' to temporarily store the serialised object.
