这个是怎么回事？没有搞明白，有谁知道这个是什么情况请告诉我！

2.eclipse 启动 找不到 jre jdk的解决方法

因为我的环境变量JAVA_HOME 完全正常，echo $JAVA_HOME没有问题，那eclipse为什么找不到jre呢？ 于是我手动配置eclipse.ini文件，在顶行加入：

hadoop@steven:~/eclipse/eclipse$ cat eclipse.ini

-vm

/usr/local/jdk1.7.0_45/jre/bin

-startup

plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20130807-1835

-product

org.eclipse.epp.package.standard.product

--launcher.defaultAction

openFile

-showsplash

org.eclipse.platform

--launcher.XXMaxPermSize

256m

--launcher.defaultAction

openFile

--launcher.appendVmargs

-vmargs

-Dosgi.requiredJavaVersion=1.6

-XX:MaxPermSize=256m

-Xms40m

-Xmx512m

这样可以访问到jre了。。。
