我使用pig拉丁语脚本,并尝试使用regex解析日志,但它在匹配双引号时返回错误”。例如:error 1200:意外字符“'”日志格式:
118.102.255.50 - - [17/Oct/2014:00:00:29 -0400] "GET /favicon.ico HTTP/1.1" 200 20 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.101 Safari/537.36"
而我写的剧本:
test = LOAD '/pigdata/log' as (line:chararray);
log = FOREACH test GENERATE FLATTEN(REGEX_EXTRACT_ALL(line,'^(\\S+)\\s+(\\S+)\\s+(\\S+)\\s+.(\\S+\\s+\\S+).\\s+\"(\\S+)\\s+(.+?)\\s+(HTTP[^\"]+)\"\\s+(\\S+)\\s+(\\S+)\\s+\"([^\"]*)\"\\s+\"(.*)\"$')) AS (address_ip: chararray, logname: chararray, user: chararray, timestamp: chararray, method: chararray, uri: chararray, proto: chararray, status: int, bytes: int, referer: chararray, userAgent: chararray);
dump log;
