Hadoop 无法在计算机上运行分布式shell

我正在尝试在纱线集群上运行分布式shell示例

@Test
public void realClusterTest() throws Exception {
System.setProperty("HADOOP_USER_NAME", "hdfs");
String[] args = {
"--jar",
APPMASTER_JAR,
"--num_containers",
"1",
"--shell_command",
"ls",
"--master_memory",
"512",
"--container_memory",
"128"
};
LOG.info("Initializing DS Client");
Client client = new Client(new Configuration());
boolean initSuccess = client.init(args);
Assert.assertTrue(initSuccess);
LOG.info("Running DS Client");
boolean result = client.run();
LOG.info("Client run completed. Result=" + result);
Assert.assertTrue(result);
}

但它在以下方面失败了：

2013-09-17 11:45:28,338 INFO [main] distributedshell.Client (Client.java:monitorApplication(600)) - Got application report from ASM for, appId=11, clientToAMToken=null, appDiagnostics=Application application_1379338026167_0011 failed 2 times due to AM Container for appattempt_1379338026167_0011_000002 exited with exitCode: 1 due to: Exception from container-launch:

.Failing this attempt..

以下是我在服务器日志中看到的内容：

2013-09-17 08:45:26,870 WARN nodemanager.DefaultContainerExecutor (DefaultContainerExecutor.java:launchContainer(213)) - Exception from container-launch with container ID: container_1379338026167_0011_02_000001 and exit code: 1

问题是我怎样才能获得更多的细节来确定哪里出了问题

PS：我们正在使用HDP2.0.5

检查纱线原木和hdfs烫发的配置。还要检查DN日志。这闻起来像是烫发问题，它无法启动作业，因为它无法登录到已配置的hdfs目录。
