我在 Ubuntu 12.04 上安装了 Apache Hadoop 1.0.4。我按照http://hadoop.apache.org/docs/stable/single_node_setup.html上的说明，到达了“执行”部分。我在 $ bin/start-all.sh 上失败了，错误消息如下。我的用户名是安森。

听起来您安装了 Hadoop Debian 软件包，并且您正试图以start-all.sh非 root 用户身份运行。

这里有一些想法：

  1. 尝试按照“独立操作”说明进行操作，该说明应按书面说明工作。
  2. 尝试按照编写的“伪分布式操作”部分进行操作，但有一个例外：sudo start-all.sh而不是bin/start-all.sh.
  3. 尝试完全卸载 Debian 软件包并改用 Hadoop 发行版 tarball。

如果您使用 tarball 选项，请首先清除 Debian 软件包：

sudo apt-get purge hadoop

确保您没有设置任何特定于 Hadoop 的环境变量。这应该什么都不返回：

set | grep HADOOP

如果您从该命令获得任何输出，请重新启动或手动unset任何包含HADOOP.

此时，您应该能够分解 tarball 并按照所写的“伪分布式操作”指南（并且作为非 root 用户）进行操作。

有两个压缩包。hadoop-1.0.4.tar.gz包括源和文档，hadoop-1.0.4-bin.tar.gz不包括。要么工作。

您用于启动 hadoop 的用户对/var/log. 检查用户对/var/log/.

hadoop.tmp.dir另一种方式，您可以跨配置更改 hadoop 基础目录 。
