1.上傳文件到linux 文件系統
2.在HDFS上
hadoop fs -mkdir /Ken
3.添加linux 文件系統的文件到HDFS
hadoop fs -put ./Findings.csv /Ken
4.建表
hive
show databases;
use default;
create table Findings(
Finding_ID_vw string,
Assessment_Type_vw string,
Short_Description_vw string,
Finding_vw string,
Status_vw string,
Criticality_vw string,
Related_Assessment_Scheduling_Record_vw string,
Master_Assessment_Name_vw string,

;
5. load 數據
load data inpath '/Ken/Findings.csv' into table Finding;

---------------------------------------------------------
如果excel file 有需要轉義的字符逗號， 或者引號 “ 和 ‘
首先把這一列的格式換成文本型text默認是general
然後再save as cvs（逗號分隔的）
最後導出來的cvs文件 文本類型的列會被 "雙引號"括起來,然後再導入hive就行了
