hive建立分区表，以当天日期（“2014-08-15”）作为分区依据，hql如下：

CREATE EXTERNAL TABLE IF NOT EXISTS product_sell(
category_id BIGINT,
province_id BIGINT,
product_id BIGINT,
price DOUBLE,
sell_num BIGINT
)
PARTITIONED BY (ds string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
LINES TERMINATED BY '\n'
STORED AS TEXTFILE;

然后以日期作为分区依据，插入数据，shell脚本如下：

#!/bin/bash
source /etc/profile;

today=$(date +%Y-%m-%d)
/usr/local/cloud/hive/bin/hive<
  
   


   
这个部分难点在于hive中不知道如何调用形如shell日期变量的方式创建日期分区，mark一下！
