使用套接字在JAVA中同时将客户端连接到多个服务器

Question

I want to implement a multi-threaded client socket in JAVA which will connect with multiple servers.. For eg.. The client will accept an array of numbers and split that array into two.. The two arrays will be sent to two servers and the result from the servers will be combined by the client to get the Final sorted array..

Any help guys???

Answer 1

Let's split the "client" meaning in 2:

1. client application, the app which you're creating which will communicate with one or more servers
2. client-socket, a client side of a communication channel, which can be connected to maximum one server at any time

As a side note, only server-sockets can handle multiple clients "at the same time"

Now, you can not have a client-socket connect to multiple servers, but you can have a client application connecting to multiple servers by having an instance of client-socket connect to each server.

So what your client application needs to do, is manage a list of client-sockets that connect to your servers, and upon receiving all the replies, aggregate the answer.

Apache hadoop是你在这种情况下必须使用的。
