ODS层设计了三个表格，分别是ods_weblog_origin（原始日志表），ods_click_pageviews（点击模型表），ods_click_stream_visit（点击流模型表），建表语句如下：
create table ods_weblog_origin( valid string, remote_addr string, remote_user string, time_local string, request string, status string, body_bytes_sent string, http_referer string, http_user_agent string) partitioned by (datestr string) row format delimited fields terminated by '\001'; create table ods_click_pageviews( session string, remote_addr string, remote_user string, time_local string, request string, visit_step string, page_staylong string, http_referer string, http_user_agent string, body_bytes_sent string, status string) partitioned by (datestr string) row format delimited fields terminated by '\001'; create table ods_click_stream_visit( session string, remote_addr string, inTime string, outTime string, inPage string, outPage string, referal string, pageVisits int) partitioned by (datestr string) row format delimited fields terminated by '\001';创建好表格后，向表格中导入数据，如下： ods_weblog_origin ods_click_stream_visit ods_click_pageviews
