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
2012/12/24 16:39:56 [alert] 13661#0: worker process 13666 exited on s
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)
添加 内容如下
<?xml version=
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml&quo
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。
核心代码
