irms模拟数据生成及数据分析 分类： H_HISTORY 2015-03-06 14:17 212人阅读 评论(0) 收藏

一、数据准备
1、每天生成随机一个文本，每小时向文本中追加2次数据，每次10万条
随机数据生成：
2,32  * * * *  bash /mnt/jediael/irms/signalGenerator/signalGenerator.sh >> /home/jediael/sg.log 2>&1
类：SignalGenerator

2、每天将前一天生成的数据文本导入HDFS
32 0 * * * bash /mnt/jediael/irms/signalGenerator/copySignalToHdfs.sh >>/home/jediael/sg.log 2>&1


二、数据分析
1、每天执行一次数据分析，将结果输出到hdfs文本中。
42 0 * * * bash /mnt/jediael/irms/signalparser/signalParser.sh >>/home/jediael/sg.log 2>&1
类：SignalParser

程序文件：
