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.
