Hive分析搜索引擎的数据(搜狗实验室数据)

    博客分类:
  • Hive
阅读更多
搜狗实验室:http://www.sogou.com/labs/resources.html
用户查询日志:http://www.sogou.com/labs/dl/q.html



将上面三种数据全部下载下来,解压后拷贝到虚拟机的/usr/local/hive/hivedata目录中;


注意:如果数据乱码的情况下,请先转成utf-8的格式,方便后面的练习;

数据格式为
访问时间\t用户ID\t[查询词]\t该URL在返回结果中的排名\t用户点击的顺序号\t用户点击的URL
其中,用户ID是根据用户使用浏览器访问搜索引擎时的Cookie信息自动赋值,即同一次使用浏览器输入的不同查询对应同一个用户ID。
第一列:时间;第二列:id;第四列:搜索关键词;第四列:关键词在搜索结果中的排名;第五列:查询结果列表中用户点击了第几个;第六列:url;

创建外部分区表
分区d设置为d=sogouq1,d=sogouq2,d=sogouq3;
hive> create external table tbsogou(id string,websession string,keyword string,search_seq int,click_seq int,website string) partitioned by (d string) row format delimited fields terminated by '\t' lines terminated by '\n';

从上面看执行情况,发现hive执行时使用了一个 job,执行时间比较长,原因有二:
1.因为自己搭建的是四台虚拟机进行测试,和生产环境的大集群没有可比性;
2.hive执行MapReduce过程本身就很慢;
执行的过程中可通过浏览器查看job运行情况:




练习:(使用分区为sogouq3的数据,因为这里面的数据相对来说多一些)
