---------------------------------

             Summary: 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
            Reporter: Yang Wang


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.
