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。。。
