### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement. ### Description Right now, there exist some tasks, that need to call a third-party platform, and query the task instance status from the third-party platform until the task instance is finished(success/failed). We can extract this logic and put it into an abstract class, the new task can easy to implement this class. <img width="770" alt="image" src="https://user-images.githubusercontent.com/22415594/180351427-34e48d98-a019-4e79-b2d0-57395b35d0d4.png";> The class defined like below: ```java public abstract class AbstractLoopTask extends AbstractTask { @Override public void handle() throws Exception { public void handle() throws Exception { LoopTaskInstanceInfo loopTaskInstanceInfo = submitTask(); sendAppIdToMaster(loopTaskInstanceInfo); LoopTaskIntstanceStatus loopTaskIntstanceStatus = LoopTaskIntstanceStatus.RUNNING; while (LoopTaskIntstanceStatus.RUNNING.equals(loopTaskIntstanceStatus)) { loopTaskIntstanceStatus = queryTaskInstanceStatus(); Thread.sleep(1000L); } } } public abstract LoopTaskInstanceInfo submitTask(); public abstract LoopTaskIntstanceStatus queryTaskInstanceStatus(); } public interface LoopTaskInstanceInfo { String getAppId(); } public enum LoopTaskIntstanceStatus { RUNNING, SUCCESS, FAILED, ; } ``` The new task only needs to override how to submit the task, and how to queryTaskInstanceStatus. Indeed, we can provide a template for the task needs to send HTTP request to submit/query. ### Use case _No response_ ### Related issues _No response_ ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
