PortableDataStream

class PortableDataStream extends Serializable

A class that allows DataStreams to be serialized and moved around by not creating them until they need to be read

Source
PortableDataStream.scala
Note

CombineFileSplit is not serializable resulting in the splitBytes construct

,

TaskAttemptContext is not serializable resulting in the confBytes construct
