Java 单节点hadoop安装Ubuntu 10.04

我遵循这个教程

我在尝试格式化hdfs文件系统时遇到此错误

/usr/local/hadoop/bin/hadoop: line 320: /usr/lib/jvm/jav-6-sun/bin/java: No such file or directory
/usr/local/hadoop/bin/hadoop: line 390: /usr/lib/jvm/jav-6-sun/bin/java: No such file or directory
/usr/local/hadoop/bin/hadoop: line 390: exec: /usr/lib/jvm/jav-6-sun/bin/java: cannot execute: No such file or directory

当我回java主页时，这就是我得到的

mco@mco-desktop:~$ echo $JAVA_HOME
/usr/lib/jvm/java-6-sun

这是我在hadoop-env.sh中的java路径

# The java implementation to use.  Required.
export JAVA_HOME=/usr/lib/jvm/jav-6-sun

---

运行Ubuntu10.04和hadoop 1.0.4这只是一个输入错误，您没有在hadoop env.sh文件中正确编写

java

。应该是这样写的：

# The java implementation to use.  Required.
export JAVA_HOME=/usr/lib/jvm/java-6-sun

而不是：

# The java implementation to use.  Required.
export JAVA_HOME=/usr/lib/jvm/jav-6-sun

考虑到这一点，不要忘记在之后重新启动集群
