业务需求:将mysql的pis.T_MATCH表导入到hive上pms库的pis_t_match表
实现代码:
hive -e "set mapred.job.queue.name=pms; create table if not exists pms.pis_t_match ( id bigint, merchant_id int, product_id string, product_name string, product_code string, oppon_product_code string, oppon_product_name string, oppon_product_url string, site_id int, score double, create_time string, creator_id string, update_time string, is_manual int, is_auto int, is_champion int, is_candidate int, is_confirm int, is_delete int, formula_ymbols int, formula_number int, remarks string, data_status int, is_barcode int, is_doubt int, is_search int, instance_id string, is_inshop int ) STORED AS TEXTFILE;"
hadoop fs -rmr /user/pms/T_MATCH sqoop import -Dmapred.job.queue.name=pms --connect jdbc:mysql://mysql-pis-slave.int.yihaodian.com:3306/pis --username pisqry --password 123456 --table T_MATCH --hive-table pms.pis_t_match --fields-terminated-by '\t' --lines-terminated-by '\n' --hive-overwrite --hive-import执行结果:
