>             Project: Beam
>          Issue Type: Bug

>            Reporter: Maximilian Michels
>            Assignee: Maximilian Michels
>            Priority: Major

> The PortableRunner doesn't pass custom PipelineOptions to the executing 
> Runner.
> Example: {{--parallelism=4}} won't be forwarded to the FlinkRunner.
> (The option is just removed during proto translation without any warning)
> We should allow some form of customization through the options, even for the 
> PortableRunner.
