Question

我有这个csv文件：

"Nom_indicateur","Modalite","Val_Quant","Val_lignes","Val_pourcentage","Date_arretee","Code_boite","Metier","Env","NOM_CRE","Application","Type"
"NB_CB","","138","3630561","","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","MAX"
"NB_CB","","0","3630561","","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","MIN"
"NB_CB","","0.4613196142414354145268458510957397","3630561","","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","MOY"
"CD_EFS","01","","1820824","50.15","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","DIS"
"CD_EFS","02","","113674","3.13","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","DIS"
"CD_EFS","03","","411607","11.34","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","DIS"
"CD_EFS","13","","19342","0.53","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","DIS"
"CD_EFS","21","","406668","11.2","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","DIS"
"CD_EFS","29","","4609","0.13","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","DIS"
"CD_EFS","56","","885","0.02","201805","1EX4","PUB_1EPSE","PR","1EPSE","InterfacePublique","DIS"

然后我创建配置单元表：

CREATE TABLE DATA_IND1 (Nom_indicateur string, Modalite string, Val_Quant double,Val_lignes int , Val_pourcentage double, Date_arretee string, Code_boite string, Metier string , Env string , NOM_CRE string,
               > Application string, Type string)
               > row format delimited fields terminated by ','
               > STORED AS TEXTFILE;

然后我将csv文件插入此表：

LOAD DATA LOCAL INPATH '/home/Data_Indicateurs8.csv' OVERWRITE INTO TABLE DATA_IND1 ;

当我需要查看前10个元素时：

看看我能得到什么结果：

 select * from DATA_IND1 limit 10;

"Nom_indicateur"        "Modalite"      NULL    NULL    NULL    "Date_arretee"  "Code_boite"    "Metier"        "Env"   "NOM_CRE"       "Application"   "Type"
"NB_CB" ""      NULL    NULL    NULL    "201805"        "1EX4"  "PUB_1EPSE"     "PR"    "1EPSE" "InterfacePublique"     "MAX"
"NB_CB" ""      NULL    NULL    NULL    "201805"        "1EX4"  "PUB_1EPSE"     "PR"    "1EPSE" "InterfacePublique"     "MIN"
"NB_CB" ""      NULL    NULL    NULL    "201805"        "1EX4"  "PUB_1EPSE"     "PR"    "1EPSE" "InterfacePublique"     "MOY"
"CD_EFS"        "01"    NULL    NULL    NULL    "201805"        "1EX4"  "PUB_1EPSE"     "PR"    "1EPSE" "InterfacePublique"     "DIS"
"CD_EFS"        "02"    NULL    NULL    NULL    "201805"        "1EX4"  "PUB_1EPSE"     "PR"    "1EPSE" "InterfacePublique"     "DIS"
"CD_EFS"        "03"    NULL    NULL    NULL    "201805"        "1EX4"  "PUB_1EPSE"     "PR"    "1EPSE" "InterfacePublique"     "DIS"
"CD_EFS"        "13"    NULL    NULL    NULL    "201805"        "1EX4"  "PUB_1EPSE"     "PR"    "1EPSE" "InterfacePublique"     "DIS"
"CD_EFS"        "21"    NULL    NULL    NULL    "201805"        "1EX4"  "PUB_1EPSE"     "PR"    "1EPSE" "InterfacePublique"     "DIS"
"CD_EFS"        "29"    NULL    NULL    NULL    "201805"        "1EX4"  "PUB_1EPSE"     "PR"    "1EPSE" "InterfacePublique"     "DIS"
Time taken: 0.382 seconds, Fetched: 10 row(s)

显示了许多Null值，它与输入的csv文件不同。

请问该如何解决？

在Hive表中插入CSV文件时获得不同的表视图
