fedora20 Eclipse for JAVAEE 关于重起后没法打开

个人环境是fedora 20,eclipse for ee 是2014年5月目前的最新版，且为官网下载。出错的情况以下：

解压后能完美运行，重起后则报错：Locking is not possible in the directory "/usr/eclipse/configuration/org.eclipse.osgi". A common reason is that the file system or Runtime Environment does not support file locking for that location. Please choose a different location, or disable file locking passing "-Dosgi.locking=none" as a VM argument.

各类百度方案均不能根治，好比提高工做空间权限，修改/usr/eclipse/configuration/org.eclipse.osgi的权限，都是当时能行，重起后又报错。后来发现我fedora的登录账号ksisn不属于sudoers管理组，也未设置过密码。最后将ksisn提高到sudoers组中就不出错了。linux新人勿喷。
