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：SignalGenerator2、每天将前一天生成的数据文本导入HDFS32 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：
