Hadoop伪分布式模式错误

我已经使用Virtualbox在OpenSuse 11.2虚拟机上设置了Hadoop。我已经完成了必要的配置。我在独立模式下成功运行了这个示例。 但在psuedo分布式模式下，我得到以下错误：

---

是你启动了Hadoop恶魔吗。与独立模式不同，这需要在psuedo dist模式下完成。您可以使用以下方式启动它们：

$bin\start all.sh

可以找到所需步骤的文档

---

你遵循了所有这些步骤吗？您可以浏览NameNode和JobTracker web界面吗？

可以尝试使用预配置的虚拟机吗？我认为这可能是开始学习hadoop的最佳方式，这些问题不应该发生在那里。

集群中似乎没有活动数据节点。是否检查状态页是否显示活动节点

---

使用命令$bin/Start-all.sh启动所有Hadoop守护进程。

这就是我尝试运行的示例。我可以浏览Namenode和JobTracker，core-site.xml文件就在那里。当我启动守护进程时，日志看起来很好。只有在“/bin/Hadoop-put conf input”之后才会发生异常。您能告诉我是否可以使用Cloudera的VM在完全分布式模式下运行Hadoop吗？每个虚拟机将在不同的计算机上运行。因为我不能在我工作的机器上安装Linux：（如果你想在不同的计算机上运行Cloudera的VM，你会遇到一些问题（与网络相关）。但是对于测试，在一台PC上运行2或3个VM是可行的。

$./bin/hadoop fs -put conf input
