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：

#!/bin/bash
