1、日志要进入的目标表结构信息
1.1 Hive库上的目标表结构信息
CREATE TABLE `yemao_log`( `id` int, `time` int, `url_from` string, `url_current` string, `url_to` string, `options` string, `uid` int, `new_visitor` string, `province` string, `city` string, `site` string, `device` string, `phone` string, `token` string, `dorm` string, `order_phone` string, `order_dormitory` string, `order_amount` string, `order_id` int, `uname` string, `site_id` int, `address` string, `dorm_id` int, `dormentry_id` int, `rid` int, `cart_quantity` string)PARTITIONED BY ( `log_date` int)ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' STORED AS INPUTFORMAT 'org.apache.hadoop.mapred.TextInputFormat' OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'LOCATION 'hdfs://Master:9000/user/hive/warehouse/yemao_log'TBLPROPERTIES ( 'transient_lastDdlTime'='1447308813');
1.2 Mysql库上当前表，其实就是一个临时表
CREATE TABLE `yemao_log` ( `id` varchar(8000) DEFAULT NULL, `time` varchar(8000) DEFAULT NULL, `url_from` text, `url_current` text, `url_to` text, `options` text, `uid` text, `new_visitor` text, `province` text, `city` text, `site` text, `device` text, `phone` text, `token` text, `dorm` text, `order_phone` text, `order_dormitory` text, `order_amount` text, `order_id` text, `uname` text, `site_id` text, `address` text, `dorm_id` text, `dormentry_id` text, `rid` text, `cart_quantity` text) ENGINE=InnoDB DEFAULT CHARSET=utf8;
1.3 Mysql库上历史表，其实就是实际在用的表CREATE TABLE `yemao_loghis` ( `id` varchar(8000) DEFAULT NULL, `time` varchar(8000) DEFAULT NULL, `url_from` text, `url_current` text, `url_to` text, `options` text, `uid` text, `new_visitor` text, `province` text, `city` text, `site` text, `device` text, `phone` text, `token` text, `dorm` text, `order_phone` text, `order_dormitory` text, `order_amount` text, `order_id` text, `uname` text, `site_id` text, `address` text, `dorm_id` text, `dormentry_id` text, `rid` text, `cart_quantity` text, `log_date` int(11) DEFAULT NULL) ENGINE=InnoDB DEFAULT CHARSET=utf8/*!50100 PARTITION BY LIST (log_date)(PARTITION p0 VALUES IN (0) ENGINE = InnoDB, PARTITION p20151109 VALUES IN (20151109) ENGINE = InnoDB, PARTITION p20151110 VALUES IN (20151110) ENGINE = InnoDB, PARTITION p20151111 VALUES IN (20151111) ENGINE = InnoDB, PARTITION p20151112 VALUES IN (20151112) ENGINE = InnoDB, PARTITION p20151113 VALUES IN (20151113) ENGINE = InnoDB, PARTITION p20151114 VALUES IN (20151114) ENGINE = InnoDB, PARTITION p20151115 VALUES IN (20151115) ENGINE = InnoDB, PARTITION p20151116 VALUES IN (20151116) ENGINE = InnoDB, PARTITION p20151117 VALUES IN (20151117) ENGINE = InnoDB, PARTITION p20151118 VALUES IN (20151118) ENGINE = InnoDB, PARTITION p20151119 VALUES IN (20151119) ENGINE = InnoDB, PARTITION p20151120 VALUES IN (20151120) ENGINE = InnoDB, PARTITION p20151121 VALUES IN (20151121) ENGINE = InnoDB, PARTITION p20151122 VALUES IN (20151122) ENGINE = InnoDB, PARTITION p20151123 VALUES IN (20151123) ENGINE = InnoDB, PARTITION p20151124 VALUES IN (20151124) ENGINE = InnoDB, PARTITION p20151125 VALUES IN (20151125) ENGINE = InnoDB, PARTITION p20151126 VALUES IN (20151126) ENGINE = InnoDB, PARTITION p20151127 VALUES IN (20151127) ENGINE = InnoDB, PARTITION p20151128 VALUES IN (20151128) ENGINE = InnoDB, PARTITION p20151129 VALUES IN (20151129) ENGINE = InnoDB, PARTITION p20151130 VALUES IN (20151130) ENGINE = InnoDB, PARTITION p20151201 VALUES IN (20151201) ENGINE = InnoDB, PARTITION p20151202 VALUES IN (20151202) ENGINE = InnoDB, PARTITION p20151203 VALUES IN (20151203) ENGINE = InnoDB) */;
2、数据处理的存储过程
CREATE DEFINER=`datahs`@`%` PROCEDURE `p_ymlog_maintain`(IN `v_log_date` int)BEGINDECLAREv_partition_exists INT;SELECTcount(1) INTO v_partition_existsFROMinformation_schema.`PARTITIONS`WHERETABLE_SCHEMA = 'logdata'AND table_name = 'yemao_loghis'AND partition_name = concat('p',v_log_date);IF v_partition_exists = 1 THENSET @exec_sql=concat("ALTER TABLE logdata.yemao_loghis DROP PARTITION p",v_log_date);PREPARE stmt FROM @exec_sql; EXECUTE stmt; END IF;SET @exec_sql=concat("ALTER TABLE logdata.yemao_loghis ADD PARTITION (PARTITION p",v_log_date,"VALUES IN (",v_log_date,"));");PREPARE stmt FROM @exec_sql; EXECUTE stmt; SET @exec_sql=concat("INSERT INTO logdata.yemao_loghis (id,time,url_from,url_current,url_to,OPTIONS,uid,new_visitor,province,city,site,device,phone,token,dorm,order_phone,order_dormitory,order_amount,order_id,uname,site_id,address,dorm_id,dormentry_id,rid,cart_quantity,log_date) SELECTa.id,a.time,a.url_from,a.url_current,a.url_to,a. OPTIONS,a.uid,a.new_visitor,a.province,a.city,a.site,a.device,a.phone,a.token,a.dorm,a.order_phone,a.order_dormitory,a.order_amount,a.order_id,a.uname,a.site_id,a.address,a.dorm_id,a.dormentry_id,a.rid,a.cart_quantity, ",v_log_date," log_dateFROMlogdata.yemao_log aWHEREid <> 'id';");PREPARE stmt FROM @exec_sql; EXECUTE stmt; TRUNCATE TABLE logdata.yemao_log;END
3、数据处理及装载的Shell脚本定时自动调度脚本
ymlog_proc.sh
只有他的好身体，没有地方可去，只想到处流浪、人生就像一场旅行，
