Hadoop 入门及简单使用

1. 介绍

官方原话为：

The Apache™ Hadoop® project develops open-source software for reliable, scalable, distributed computing.

The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures.

翻译过来就是hadoop贡献了一个可靠，大规模，分布式的计算开源软件(通常一个公司开发出产品在第一句话都要吹一下的，还都是一堆听起来很高大尚的专业术语
