描述：
Hive表pms.cross_sale_path建立以日期作为分区，将hdfs目录/user/pms/workspace/ouyangyewei/testUsertrack/job1Output/crossSale上的数据，写入该表的$yesterday分区上
表结构：
hive -e " set mapred.job.queue.name=pms; drop table if exists pms.cross_sale_path; create external table pms.cross_sale_path ( track_id string, track_time string, session_id string, gu_id string, end_user_id string, page_category_id bigint, algorithm_id int, is_add_cart int, rcmd_product_id bigint, product_id bigint, category_id bigint, path_id string, path_type int, path_length int, path_list string, order_code string ) PARTITIONED BY (ds string) ROW FORMAT DELIMITED FIELDS TERMINATED BY 't' LINES TERMINATED BY 'n' STORED AS TEXTFILE;"
写法：
yesterday=`date -d -1days %Y-%m-%d` hive -e "load data inpath '/user/pms/workspace/ouyangyewei/testUsertrack/job1Output/crossSale' into table pms.cross_sale_path partition(ds='$yesterday');"
