Question

我有一个存储在HDFS中的Apache组合日志文件。以下是前五行的示例：

123.125.67.216 - - [02/Jan/2012:00:48:27 -0800] "GET /wiki/Dekart HTTP/1.1" 200 4512 "-" "Mozilla/5.0 (Windows NT 5.1; rv:6.0.2) Gecko/20100101 Firefox/6.0.2"

123.125.67.213 - - [02/Jan/2012:00:48:33 -0800] "GET / HTTP/1.1" 301 433 "-" "Mozilla/5.0 (Windows NT 5.1; rv:6.0.2) Gecko/20100101 Firefox/6.0.2" 
123.125.67.214 - - [02/Jan/2012:00:48:33 -0800] "GET /wiki/Main_Page HTTP/1.1" 200 8647 "-" "Mozilla/5.0 (Windows NT 5.1; rv:6.0.2) Gecko/20100101 Firefox/6.0.2"

我正在尝试使用piggybank中的CombinedLogLoader使用Apache Pig加载此文件。这应该工作。这是我的示例代码：

grunt> raw = LOAD 'log' USING org.apache.pig.piggybank.storage.apachelog.CombinedLogLoader AS (remoteAddr, remoteLogname, user, time, method, uri, proto, status, bytes, referer, userAgent);
16/02/15 21:39:38 INFO Configuration.deprecation: fs.default.name is deprecated. Instead, use fs.defaultFS
grunt> dump raw;

我得到0条记录，即使文件有数千条。

以下是我的完整输出。我做错了什么？

Answer 1

确保您的日志文件格式正确。我注意到你的日志文件在行的边缘包含vector_arg.erase(vector_arg.begin() + index_arg)。移除space并执行相同的脚本。请参阅我已执行您的脚本，结果如下所示。

<强>脚本：

space

<强>输出：

grunt> LOAD '~/temp1.log' USING org.apache.pig.piggybank.storage.apachelog.CombinedLogLoader AS (remoteAddr, remoteLogname, user, time, method, uri, proto, status, bytes, referer, userAgent);    
grunt> dump raw;

org.apache.pig.piggybank.storage.apachelog.CombinedLogLoader不以组合文件格式加载文件
