需求：将hive里数据按月按天处理后导入另一个表中：
#!/usr/bin/env bash
year=$1
m=$2
len=${#m}
if [ $len == 1 ]
then
month="0"$m
else
month=$m
fi
d=$3
day=0
for i in $(seq 1 $d)
do
length=${#i}
if [ $length == 1 ]
then
day="0"$i
else
day=$i
fi
#echo $length,$i,$day
insert_sql="set mapreduce.job.queuename=bi; insert into my_schema.daily_slot_info select i.ymd , i.adslot_id as slot_id , imp, clk from ( select concat(year,month,day) as ymd, adslot_id, count(zid) as imp from your.imp_t t where year='$year' and month='$month' and day='$day' and vendor_id= 9 group by concat(year,month,day), adslot_id ) i left join ( select concat(year,month,day) as ymd , adslot_id, count(zid) as clk from your.clk_t t where year='$year' and month='$month' and day='$day' and vendor_id = 9 group by concat(year,month,day), adslot_id ) c on i.ymd = c.ymd and i.adslot_id = c.adslot_id ;"
echo $insert_sql
hive -e "$insert_sql"
exit_code=$?
if [ $exit_code -eq 0 ];then
echo "$month $day successful!"
else
echo "error at $month $day"
exit $exit_code
fi
done
