------------------------------------
Summary: Allow RpcEndpoint#postStop to complete asynchronously
Key: FLINK-8665
URL: https://issues.apache.org/jira/browse/FLINK-8665
Project: Flink
Issue Type: Sub-task
Components: Distributed Coordination
Affects Versions: 1.5.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.5.0
Every {{RpcEndpoint}} should have the possibility to trigger asynchronous clean
up operations in its {{RpcEndpoint#postStop}} method. In order to do that the
{{postStop}} method should return a {{CompletableFuture<Void>}} which is
completed once all post stop actions have finished. The
{{RpcEndpoint#terminationFuture}} will only be completed afterwards.
