[jira] [Created] (FLINK-8382) sheduleRunAsync with a positive
schedule delay does not work in JobMaster
Zhu Zhu created FLINK-8382:
------------------------------
Summary: sheduleRunAsync with a positive schedule delay does not work in JobMaster
Key: FLINK-8382
URL: https://issues.apache.org/jira/browse/FLINK-8382
Project: Flink
Issue Type: Bug
Components: Distributed Coordination
Affects Versions: 1.5.0
Reporter: Zhu Zhu
Here's the process of invoking scheduleRunAsync in JM:
1. The method scheduleRunAsync in JobMaster will forward a RunAsync message to FencedAkkaRpcActor.
2. FencedAkkaRpcActor handles it with method handleRunAsync from its parent class AkkaRpcActor: If the schedule delay is positive, handleRunAsync will schedule a raw RunAsync message without a FencedMessage/UnfencedMessage wrapped.
3. Later when FencedAkkaRpcActor receives the scheduled raw RunAsync message, it will discard it for not recognizing the message type.
Thus the scheduleRunAsync does work.
