[jira] [Created] (FLINK-2430) Potential race condition when restart
all is called for a Twill runnable
Henry Saputra created FLINK-2430:
------------------------------------
Summary: Potential race condition when restart all is called for a Twill runnable
Key: FLINK-2430
URL: https://issues.apache.org/jira/browse/FLINK-2430
Project: Flink
Issue Type: Bug
Affects Versions: 0.6-incubating
Reporter: Henry Saputra
When sending restart instance to all for a particular TwillRunnable, it could have race condition where the heartbeat thread run right after all containers have been released which make the check:
// Looks for containers requests.
if (provisioning.isEmpty() && runnableContainerRequests.isEmpty() && runningContainers.isEmpty()) {
LOG.info("All containers completed. Shutting down application master.");
break;
}
This could happen when all running containers are empty and new runnableContainerRequests has not been added.
