extends Event

Events used by TezRootInputInitializer implementations to provide the user payload for individual tasks running as part of the Vertex for which an Initial Input has been configured. This event is used by InputInitialziers to configure tasks belonging to a Vertex. The event may be processed by a @link VertexManagerPlugin before being sent to tasks. A TezRootInputInitializer may send Events with or without a serialized user payload. Events, after being processed by a VertexManagerPlugin, must contained the payload in a serialized form.
