Apache Kylin1.5.2.1之订单案例详细构建流程
转：http://blog.itpub.net/30089851/viewspace-2122586/
一.Hive订单数据仓库构建
1. 创建事实表并插入数据
DROP TABLE IF EXISTS default.fact_order ;
create table default.fact_order (
time_key string,
product_key string,
salesperson_key string,
custom_key string,
quantity_ordered bigint,
order_dollars bigint,
cost_dollars bigint
)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ','
STORED AS TEXTFILE;
load data local inpath '/root/kylinsample/fact_order.txt' overwrite into table default.fact_order;
