hadoop hdfs csv導入hive表

create table toys.test
(id int, x0 double, x1 double, x2 double, x3 double)
row format delimited fields terminated by ',' stored as textfile;

　先在hive 數據庫toys創建表test,注意行分割符號為，逗號

 

上傳本地數據到hdfs

hadoop fs -put  /data/projects/breast.csv    /data/projects/breast.csv

hdfs上傳到hive

LOAD DATA INPATH  '/data/projects/breast.csv'   overwrite into table  toys.test ;
