And if you can speed up domain resolution in some way, you can speed up surfing the internet, here is an acceleration method: use
DNS is used whenever you use the Internet. Every time you send an email or surf the internet, you must rely on DNS. DNS is responsible for the ing between host names and interconnected network addresses, which is handled by computers. If the connection to the DNS server is delayed, or if the DNS server resolves an address too long, the access will be delayed.

anyone who wants to learn. Today, we can all connect to the Internet.
But you must remember that when you connect to the Internet, your computer becomes the target of an attack. Become the target of viruses, Trojans, and other programs.

Follow the order of classes in the package order, because I don't understand the relationship between the specific system of the hadoop class and the class, if you have accumulated some knowledge, you can look at other people's hadoop source code interpretation class book, similar to the http://pan.baidu.com/s/1i3GGvvZ.
