tison commented on FLINK-10400:
-------------------------------
Agree. It is a code wart that should be fixed.
To be more clear, return a {{JobResult}} with {{Exception}} as described,
{{addSuppressed}} if there is a failure cause.
> Return failed JobResult if job terminates in state FAILED or CANCELED

> URL: https://issues.apache.org/jira/browse/FLINK-10400
> Project: Flink
> Issue Type: Bug
> Components: Client
> Affects Versions: 1.6.1, 1.7.0, 1.5.4
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Major
> Fix For: 1.7.0, 1.6.2, 1.5.5

>
> If the job reaches the globally terminal state {{FAILED}} or {{CANCELED}},
> the {{JobResult}} must return a non-successful result. At the moment, it can
> happen that in the {{CANCELED}} state where we don't find a failure cause
> that we return a successful {{JobResult}}.
> In order to change this I propose to always return a {{JobResult}} with a
> {{JobCancellationException}} in case of {{CANCELED}} and a
> {{JobExecutionException}} in case of {{FAILED}}.
