配置好hadoop后开始安装eclipse，又有问题了。解压后的文件不存在！

这是我的eclipse版本，官网下的：
eclipse-jee-luna-SR1-linux-gtk-x86_64.tar.gz

然后放到了/opt目录下，执行解压命令
tar -zxvf /opt/eclipse-jee-luna-SR1-linux-gtk-x86_64.tar.gz

然后，进入了/opt目录根本没有eclipse
root@localhost:/opt# ls -a
. .. eclipse eclipse-jee-luna-SR1-linux-gtk-x86_64.tar.gz

本人是个linux渣渣，大神们求助啊~~~万分感谢~~
