------------------------------------
Resolution: Fixed
> Make ResourceManager#internalDeregisterApplication and implementation
> asynchronous
> ----------------------------------------------------------------------------------
>
> Key: FLINK-17154
> URL: https://issues.apache.org/jira/browse/FLINK-17154
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / Kubernetes, Deployment / Mesos, Deployment
> / YARN, Runtime / Coordination
> Affects Versions: 1.12.0
> Reporter: Yang Wang
> Priority: Minor
> Labels: auto-deprioritized-major
>
> Follow the discussion in this PR[1].
> Currently, {{ResourceManager#internalDeregisterApplication}} is a blocking
> call, so all the specific deployment implementation will do the Flink cluster
> deregister synchronously.
> After FLINK-17024, we could get a safe thread pool to execute the I/O
> operations, including the "deregister". This ticket is to make the interface
> asynchronous. Benefit from this, the shutdown process will be a little
> faster.
