`ProgramInvocationException` are thrown during execution of the user
program. `JobExecutionException` is thrown while the job is executing. That
makes much more sense IMHO. The API doesn't strictly define any exceptions
(`throws Exception`). Thus, we're not breaking.

> Key: FLINK-4272
> URL: https://issues.apache.org/jira/browse/FLINK-4272
> Project: Flink
> Issue Type: New Feature
> Components: Client
> Reporter: Maximilian Michels
> Assignee: Maximilian Michels
> Priority: Minor
> Fix For: 1.2.0
>
>
> The aim of this new features is to expose a client to the user which allows
> to cancel a running job, retrieve accumulators for a running job, or perform
> other actions in the future. Let's call it {{JobClient}} for now (although
> this clashes with the existing JobClient class which could be renamed to
> JobClientActorUtils instead).
> The new client should be returned from the {{ClusterClient}} class upon job
> submission. The client should also be instantiatable by the users to retrieve
> the JobClient with a JobID.
> We should expose the new JobClient to the Java and Scala APIs using a new
> method on the {{ExecutionEnvironment}} / {{StreamExecutionEnvironment}}
> called {{executeWithControl()}} (perhaps we can find a better name).
