昨晚和朋友聊天，喝了点咖啡，由于我经常喝茶，很长时间没喝咖啡了，所以失眠了，于是起床读JVM规范，读完后在朋友圈发了一条信息：
JVM Run-Time Data Areas：The Java Virtual Machine defines various run-time data areas that are used during execution of a program. So
Spark SQL supports most commonly used features of HiveQL. However, different HiveQL statements are executed in different manners:
1. DDL statements (e.g. CREATE TABLE, DROP TABLE, etc.)
nginx在运行过程中是否稳定，是否有异常退出过？这里总结几项平时会用到的小技巧。
1. 在error.log中查看是否有signal项，如果有，看看signal是多少。
比如，这是一个异常退出的情况：
$grep signal error.log

方法一：常用方法 关闭XML验证
工具栏：windows => preferences => xml => xml files => validation => Indicate when no grammar is specified:选择Ignore即可。
方法二：（个人推荐）

最主要的是使用到了一个jquery的插件jquery.media.js，使用这个插件就很容易实现了。
