Hadoop 向Thread提交wordcount示例（SchedulerUtils.validateResourceRequest中的例外）

我得到以下例外情况：

我是否设置了无效的资源？我试图让代码活起来

我发现，

NullPointerException

是从

ShedulerUtils.java@line 196

抛出的，它是：

if（resReq.getCapability（）.getMemory（）<0||
resReq.getCapability（）.getMemory（）>maximumResource.getMemory（））{
抛出新的InvalidResourceRequestException（“无效资源请求”
+，请求的内存<0
+，或请求的内存>配置的最大值
+，requestedMemory=“+resReq.getCapability（）.getMemory（）
+，maxMemory=“+maximumResource.getMemory（））；
}

所以我可能没有为容器设置功能（内存）。我该怎么做

我试过：

Resource capability=Records.newRecord（Resource.class）；
能力。设置内存（amMemory）；
setResource（能力）

但是
ContainerLaunchContext amContainer
没有方法
setResource

我正在运行Hadoop 2.2.0。
我必须将
功能
授予
应用程序SubmissionContext
，而不是
容器启动上下文
，如示例所示

此外，我还将Hadoop更新为2.3.0
