shell实现数据质量小功能

step_1 — 创建临时表，模拟数据质量监控情况
create table if not exists dataintel_tmp.qzd_20211026_sjzl_v1 as
select 0 as a
,null as b
,null as c
,null as d
,null as e
,0 as f
,0 as g
,0 as h
,0 as i
,3 as j
,6 as k
,7 as l
,12 as m

step_2 (done)
— 暂未找到 hive中统计字段数的方法
— 假定每张表字段穷举计算

针对每张表跳板机中空跑的情况 (done)

day=date -d"-1 days" +"%Y%m%d"
if [ $# -eq 1 ];then
day=$1
fi
count=0
while
[ $count -eq 0 ]
do
sh xxxx.sh KaTeX parse error: Undefined control sequence: at position 84: …utformat=csv2 ̲ ̲ …{day}"`
echo $count
done

step_3 针对结果异常占比情况返回特定的异常值(done)
