将 LAN 上的视频分发到备用位置 - 浏览器可以检测到这一点吗？
我是公司内部网的管理员，我想开始制作视频。然而，我们的位置之间有一个非常小的带宽隧道，我想避免通过多个用户流式传输视频来占用它。
我想将文件同步到每个位置的服务器。然后我希望浏览器（或内联网）检测我所在的站点。从那里，我希望它从最近的位置请求视频。
我从来没有这样做过，想知道是否已经有解决方案。看起来 Hadoop 可能会做到这一点，但我想在我决定学习它之前，我想听听使用它的人的说法。
I'm the administrator for a company intranet and I'd like to start producing videos. However, we have a very small bandwidth tunnel between our locations, and I'd like to avoid hogging it by streaming videos by multiple users.
I'd like to synchronize the files to servers at each of the locations. Then I'd like the browser (or the intranet) to detect which site I'm at. From there, I'd like it to request the video from the closest location.
I've never done this, and was wondering if there is already a solution out there for this. It looks like Hadoop may do this, but I guess I'd like to hear that from someone using it before I commit to learning it.

我不知道如何实现你想要的，但hadoop并没有做你想要的。
Hadoop 提供了在分布式环境（集群）中处理大量数据（例如日志文件分析）的基础设施，但集群中的机器通常通过高速通信链路连接（甚至可能位于同一服务器机架上）。
所以我可以回答你问题的最后一部分，并告诉你hadoop 不太适合你的问题类型。不过，您可能仍然想了解 hadoop 为您提供了什么，以便您可以在其他场景中使用它。
您可能还想查看 serverfault 来查找问题的答案，因为您似乎正在寻找更像系统管理员的答案，而不是编程一.
这里是学习 hadoop 的好材料
I don't know how to achieve exactly what you want, but hadoop does not do what you desire.
Hadoop provides an infrastructure to process large amounts of data (like e.g. log file analysis) in a distributed environment (cluster) but the machines in the cluster are usually connected with high speed communication links (may be even on the same server rack).
So I can answer the last part of your question and tell you that hadoop not a good fit for your type of problem. You might still want to learn what hadoop gives you, so that you may be able to use it in another scenario, though.
You might also want to check out serverfault to find an answer to your problem, as it seems you are looking to a more system administrator like answer than a programming one.
Here are good materials to learn about hadoop
