针对当前云服务发展中遇到的数据量急速增加为后台数据中心带来的数据处理问题，本文实施了Hadoop 的 性能测试。首先对云计算异构环境的Hadoop 性能进行了描述，其次对Hadoop 集群中两种节点的性能差别进行了分析，并给 出了实验异构的平台的设计和实验结果。

In view of the data processing problems in data center brought by the Rapid increase in data volume in the current development of cloud services, this article carries out the Hadoop performance testing. Firstly it describes to the Hadoop performance under cloud computing heterogeneous environment, then analyzes differences of performance between two kinds of nodes in Hadoop cluster, and gives out the experiment design and experimental results of heterogeneous platform.
