> h2. Why
> In our internal streaming platform, we will use flink-cli tool to submit Flink streaming application on Yarn.
> However when encountering Hadoop cluster down and then lots of flink apps need to be resubmitted, the submitter of worker in our platform will hang at this time.
> Because the Yarn cluster resources are tight and the scheduling efficiency becomes low when lots of apps needs to be started.
> And flink-cli will not exit until the app status changes to running.
> In addition, I also think there is no need to wait when app status is accepted with detach mode on Yarn.
> h2. How
> When app in accpeted status, flink-cli should exit directly to release submitter worker process resource. The PR could refer to : https://github.com/apache/flink/blob/f191becdb42d6df823a103dc4f787c4737baa8e7/flink-yarn/src/main/java/org/apache/flink/yarn/YarnClusterDescriptor.java#L1224
