区块链引发了世界性的关注，迅速地成为一场全球参与竞逐的“军备”大赛，许多国家认识到区块链技术巨大的应用前景，开始从国家层面设计区块链的发展道路。 2017年，区块链及相关行业加速发展，全球正在跑步进入“区块链经济时代”。在全球范围内，会出现更多的成熟应用。此时此刻，中国面临重大机遇。

由于教育领域自身的独特性和复杂性，区块链技术的应用也面临教育应用推广运行难、教育数据产权模糊、数据 存储空间有限以及区块链技术自身安全隐患所引起的师生隐私保护风险等诸多挑战。

Hadoop is a Java-based distributed framework designed to work with applications implemented using MapReduce modeling. This distributed framework makes it possible to pass the load on to thousands of nodes across the whole Hadoop cluster. The nature of distributed framework also allows for node failure without cluster failure. The Hadoop market is predicted to grow at a compound annual growth rate over the next several years. Several good tools and guides describe how to deploy Hadoop clusters, but very little documentation tells how to increase performance on a Hadoop cluster once it is deployed. This white paper explains several BIOS, OS, file system, Hadoop and Java tunings that can increase performance of a Hadoop cluster. These performance tunings require changes to the BIOS,OS, Hadoop and JVM configuration files.
