---------------------------------
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.
