Taking Typhoon Precipitation Model for Example
Geographical Information System, School of Geographical Sciences
Abstract:In recent years, with the maturity and popularity of the distributed parallel computing technology, computing intensive scientific research with new ideas, that the use of low-cost, scalable, distributed cluster instead of the traditional high-performance servers . The purpose of this paper is to you typhoon precipitation forecast, for example, research the possibility of space objects based on Hadoop distributed computing and effectiveness.In order to better evaluate the value of Hadoop in GIS research, the case study using parallel artificial neural network - genetic algorithm to simulate a sufficient density calculation. Keywords:Typhoon Precipitation Hadoop Genetic BP-ANN
The project is completed at my student age. So I didn't use maven to manage the dependencies and build process(I didn't know maven at that time). I was use ANT to compile code and publish jobs to the Hadoop Cluster.
And the project NOT contained
the data. The data isn't open data and I have not been authorized to publish the data :(

nchc.org.tw: Thanks for their Hadoop Cluster and help me to delete the huge out of controller log :P
- build 编译结果
- conf 配置文件
- data 项目数据
- dist 发行版目录
- lib 开发类库
- logs 开发日志文件
- relib 发行版类库
- src 源码
- 项目是使用ANT 1.9 构建的
- 运行项目的时候要配置Build.xml里面的相关信息
- 项目中用到了ANT的SSH插件,如果使用原生ANT需要另外添加SSH插件
- 项目主函数入口为 MosterDriver,里面封装了项目用到的MapReduce计算的一些实现,使用参照Build.xml文件中的DataJoin脚本
