这篇文章是我来Hulu这一年做的主要工作,结合当下流行的两个开源方案Docker和YARN,提供了一套灵活的编程模型,目前支持DAG编程模型,将会支持长服务编程模型. 基于Voidbox,开发者可以很容易的写出一个分布式的框架,Docker作为运行的执行引擎,YARN作为集群资源的管理系统. 同时这篇文章也发表在Hulu官方的技术博客上:http://tech.hulu.com/blog/2015/08/06/voidbox-docker-on-yarn/ csdn在线:http://huiyi…

前言 在以往的java开发中,程序员最怕大量的配置,是因为配置一多就不好统一管理,经常出现找不到配置的情况.而项目中,从开发测试环境到生产环境,往往需要切换不同的配置,如测试数据库连接换成生产数据库连接,若有一处配错或遗漏,就会带来不可挽回的损失.正因为这样,spring boot给出了非常理想的解决方案——application.properties.见application-properties的官方文档:http://docs.spring.io/spring-boot/docs/curr…

Android权限分的很细,但命名比较人性化,Android permission比SymbianCapabilities有了不少改进,下面就来看看权限许可都有哪些定义吧,发现还是比较繁多的,如果发现你的程序某个地方调试错误很可能是Androidpermission的访问控制在作怪,这也是为了安全防止手机成为病毒的场所.Android开发网获取到的消息来看不用购买高昂的数字签名证书,权限许可权由用户决定而不是手机制造商和平台提供商,这一点不得不说明为Android开发人员着想,下面的信息都是需要…
