当我尝试从 shell 启动 Ubuntu 中的 Hadoop 集群时，出现以下错误：

    hduser@duleep-G31M-S2L:/usr/local/hadoop$ /usr/local/hadoop/bin/start-all.sh
/usr/local/hadoop/libexec/../conf/hadoop-env.sh: line 9: export: `/usr/lib/jvm/jdk1.7.0_09': not a valid identifier

如果您知道出了什么问题，请帮忙。

检查$HADOOP_HOME/conf/hadoop-env.sh脚本的内容，以获取 JAVA_HOME 导出行 - 看起来您在那里有一个尾随引号。

作为参考，这是我拥有的版本：

# The java implementation to use.  Required.
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_07-i586

如果您仍然遇到问题，请将您的输入粘贴回您的原始问题

要使用的 java 实现。

改变这个

#export JAVA_HOME=/usr/lib/jvm/jdk1.5.0

至

export JAVA_HOME=/usr/lib/jvm/jdk1.6.0
