TisonKun commented on issue #5931: [FLINK-9190][flip6,yarn] Request new
container if container completed unexpectedly
URL: https://github.com/apache/flink/pull/5931#issuecomment-417558343
@tillrohrmann thanks for your reply. Here is one more question.
Does `ResourceManager` asks for slot by itself? With current codebase
`ResourceManager` would ask for new worker as container complete unexpectedly.
What if `ExecutionGraph` failover concurrent to `ResourceManager` asks for new
worker? Is there one more extra worker be started?

> *Description*
> The {{YarnResourceManager}} does not request new containers if
> {{TaskManagers}} are killed rapidly in succession. After 5 minutes the job is
> restarted due to {{NoResourceAvailableException}}, and the job runs normally
> afterwards. I suspect that {{TaskManager}} failures are not registered if the
> failure occurs before the {{TaskManager}} registers with the master. Logs are
> attached; I added additional log statements to
> {{YarnResourceManager.onContainersCompleted}} and
> {{YarnResourceManager.onContainersAllocated}}.
> *Expected Behavior*
> The {{YarnResourceManager}} should recognize that the container is completed
> and keep requesting new containers. The job should run as soon as resources
> are available.
