Question

当我尝试从shell启动Ubuntu中的Hadoop集群时，我收到以下错误：

    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

如果你知道什么是错的，请帮忙。

Answer 1

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

供参考，这就是我的版本：

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

Answer 2

要使用的java实现。

更改此

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

到

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