--------------------------------------
[~trohrmann]
Polling is always OK.
However, when in our internal platform, we integrate Flink batch into
apache/Oozie. If having this feature, we don't need to poll. And it will make
easy to integrate with other projects.
I think this is a usability improvement. By the way, perjob mode also support
attach.
Of source, if no this feature, other solutions also could solve it.

> h2. Why
> In our internal data platform, we support flink batch and streaming job
> submission. To reduce the submission worker overload, we use the Flink
> application mode to submit flink job. It's a nice feature!
> However, on batch mode, we hope flink client couldn't exit until the batch
> application finished (No need to get job result, just wait). Now the flink
> lack this feature, and it is not stated in the document that Application Mode
> does not support attach.
