> Currently, the ContainerLocalizer to NM heartbeats to the NM every second.
> Not very significant, but this causes a ~4second delay in jobs (job jar,
> splits, etc). Instead, it should heartbeat to ask for additional resources to
> localize as soon as the previous one is localzied. There's already a TODO in
> the ContainerLocalizer for this.
