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，请提供帮助。
最佳答案
检查您的$HADOOP_HOME/conf/hadoop-env.sh脚本的内容，以获取JAVA_HOME导出行-好像您的行尾带有引号。
供引用，这是我的版本:
# The java implementation to use. Required.
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_07-i586
如果仍然有问题，请将您的输入内容粘贴回原始问题中
