> *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.
