["Pei He (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEAM-443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15609642#comment-15609642 ] 

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.

> 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.
