> 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.
