Gopher  China  2015  Resource  Scheduling  &  Container  Technology  for  Financial  Service  动态资源管理和容器技术  在金融行业的架构探索和明天  余军  Gopher  China  2015  Gopher  China  2015  China  2015  求解之路的探索  n 他们是否解决了我们的问题?  n No   ① Mesos  采用了DRF(Dominant  Resource  Fairness)  调度机制。 YARN自带FIFO、Capacity  Scheduler和Fair  Scheduler(借鉴了 Mesos的DRF)。  ② Mes oop中Capacity  Scheduler的调度机制，将所有资源分成若干个queue，每个 queue分配一定量的资源，每个user有一定的资源使用上限。  ③ Mesos采用了Resource  Offer机制，这种调度机制面临着资源碎 片问题，即：每个节点上的资源不可能全部被分配完，剩下的一 点可能不足以让任何任务运行，这样，便产生了类似于操作系统 中的内存碎片问题。 

that take a user-suppiled lambda to generate the data needed to render our desired compile-time resource! These are e�ectively templated functions, but we will use the cleaner auto parameter syntax for
