Spark日志分析

根据tomcat日志计算url访问了情况，具体的url如下，
要求：区别统计GET和POST URL访问量
结果为：访问方式、URL、访问量

//textFile() 加载数据
val data = sc.textFile("/spark/seven.txt")

//filter 过滤长度小于0， 过滤不包含GET与POST的URL
val filtered = data.filter(_.length()>0).filter( line => (line.indexOf("GET")>0 || line.indexOf("POST")>0) )

//转换成键值对操作
val res = filtered.map( line => {
if(line.indexOf("GET")>0){ //截取 GET 到URL的字符串
(line.substring(line.indexOf("GET"),line.indexOf("HTTP/1.0")).trim,1)
}else{   //截取 POST 到URL的字符串
(line.substring(line.indexOf("POST"),line.indexOf("HTTP/1.0")).trim,1)
}//最后通过reduceByKey求sum
}).reduceByKey(_+_)

//触发action事件执行
res.collect()
