如何在使用Spring纱线时将资源分配给容器？

我正在[github][1]上尝试Spring纱线示例，该示例由gradle构建。我成功地在Thread上运行了custom amservice示例

但我不知道如何为容器分配特殊资源。我尝试在CustomAppmaster的StaticEventingAppmaster类中重写onContainerAllocated和onContainerLaunched方法并分配资源，如下所示

@Override
protected void onContainerAllocated(Container container) {
       //==allocate resource
        Resource resource = new ResourcePBImpl();
        resource.setMemory(1300);
        resource.setVirtualCores(7);
        container.setResource(resource);
        //====
        if (getMonitor() instanceof ContainerAware) {
                ((ContainerAware)getMonitor()).onContainer(Arrays.asList(container));
        }
        getLauncher().launchContainer(container, getCommands());
}
@Override
protected void onContainerLaunched(Container container) {
       //==allocate resource
        Resource resource = new ResourcePBImpl();
        resource.setMemory(1300);
        resource.setVirtualCores(7);
        container.setResource(resource);
        //====
        if (getMonitor() instanceof ContainerAware) {
                ((ContainerAware)getMonitor()).onContainer(Arrays.asList(container));
        }
}

在日志中，它似乎是有效的：

关键点是，在日志中：。当前使用情况：使用了86.6 MB的1 GB物理内存，而不是1.3 GB

所以我认为我的方法没有起作用。有谁能告诉我如何正确分配资源吗？

这是《纱线》中的一个问题领域，我相信随着越来越多的非MR应用程序在《纱线》中使用，这一领域最终会变得更好。我相信您的设置是正确的，但纱线的一点奇怪行为导致了这些问题。目前，从应用程序的角度来看，我们所能做的很少，因为大多数mem设置都是在纱线本身中强制执行的，来自应用程序的请求只是请求

纱线上的Spring XD依赖于同样的东西，值得检查我们在其文档中写的内容：。请参阅“配置内存保留”部分

我会尽力确保同样的信息也会传到我们的SpringHadoop和SpringThreadRef文档中
