今天做了企业发票异常分析的作业成功地将数据导入到hive数据仓当中，并对数据进行了初步的清洗
流程如下：
一．将三个样表文件中的数据导入HIVE数据仓库中
先建三个表：
create table xxfpb(
hydm string,
xf_id string,
djzclx_dm string,
kydjrq string,
xgrq string,
label string,
fp_nid string,
je double,
se double,
jshj double,
kpyf string,
kprq string,
zfbz string
)row format delimited fields terminated by ',';
其余两个表的建表语句类似
然后进行数据清洗：
insert overwrite table nsrxx select substring(hydm,2,length(hydm)-1) as hydm, nsr_id as nsr_id,djzclx_dm as djzclx_dm,kydjrq as kydjrq,xgrq as xgrq,substring(label,1,length(label)-1) as label from nsrxx;
insert overwrite table zzsfp_hwmx select substring(fp_nid,2,length(fp_nid)-1) as fp_nid, date_kry as date_kry,hwmc as hwmc,ggxh as ggxh,dw as dw,sl as sl,dj as dj,je as je,se as se,substring(spbm,1,length(spbm)-1) as spbm from zzsfp_hwmx;
清洗的目的是将三个表的前括号和后括号去掉
