Pei He commented on BEAM-443:
-----------------------------
reopen the jira because there are more discussions about:
1. whether waitUntilFinish should throw exceptions.
2. whether it should throw checked or unchecked exceptions.
> PipelineResult needs waitUntilFinish() and cancel()
> ---------------------------------------------------

>
> waitToFinish() and cancel() are two most common operations for users to
> interact with a started pipeline.
> Right now, they are only available in DataflowPipelineJob. But, it is better
> to move them to the common interface, so people can start implement them in
> other runners, and runner agnostic code can interact with PipelineResult
> better.
