Description

In ContainerManagerImpl#startContainerInternal, a duplicate store container request is sent to NM State store which is unnecessary.

        this.context.getNMStateStore().storeContainer(containerId,
            containerTokenIdentifier.getVersion(), request);
        dispatcher.getEventHandler().handle(
          new ApplicationContainerInitEvent(container));
        this.context.getNMStateStore().storeContainer(containerId,
            containerTokenIdentifier.getVersion(), request);
