[jira] [Created] (FLINK-5176) Properly wait for component shutdown
in Runner components
Till Rohrmann created FLINK-5176:
------------------------------------
Summary: Properly wait for component shutdown in Runner components
Key: FLINK-5176
URL: https://issues.apache.org/jira/browse/FLINK-5176
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination
Reporter: Till Rohrmann
Priority: Minor
Currently, the different runners for the Flip-6 components {{JobMaster}}, {{ResourceManager}} and {{TaskExecutor}} don't wait until the component has been shut down in their own {{shutDown}} method. The problem is that the {{AkkaRpcService}} implements the {{RpcService#shutDown}} method via a {{PoisonPill}} which is not executed synchronously. Instead we should obtain the {{RpcEndpoint#getTerminationFutures}} and wait on the returned future (with a given timeout).
