> Race condition in LocalizerRunner causes container localization timeout.
> Currently LocalizerRunner will kill the ContainerLocalizer when pending list
> for LocalizerResourceRequestEvent is empty.
> {code}
> } else if (pending.isEmpty()) {
> action = LocalizerAction.DIE;
> }
> {code}
> If a LocalizerResourceRequestEvent is added after LocalizerRunner kill the
> ContainerLocalizer due to empty pending list, this
> LocalizerResourceRequestEvent will never be handled.
> Without ContainerLocalizer, LocalizerRunner#update will never be called.
> The container will stay at LOCALIZING state, until the container is killed by
> AM due to TASK_TIMEOUT.
