--------------------------------------
[~wangyang0918] Thanks for your reply.

I am afraid that depending on the attach mode is not reliable since the Flink
client may disconnect because of network issues or JobManager failover.

I'm doubt whether the above problems will also occur when in per-job attach
mode.

> 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.
