DetachedApplicationRunner (Flink : Clients 2.0.1 API)

java.lang.Object
- org.apache.flink.client.deployment.application.DetachedApplicationRunner

All Implemented Interfaces:

ApplicationRunner
```
@Internal
public class DetachedApplicationRunner
extends Object
implements ApplicationRunner
```
An ApplicationRunner which runs the user specified application using the EmbeddedExecutor. This runner invokes methods of the provided DispatcherGateway directly, and it does not go through the REST API.
In addition, this runner does not wait for the application to finish, but it submits the application in a DETACHED mode. As a consequence, applications with jobs that rely on operations like [collect, print, printToErr, count] will fail.
