hive 導入csv文件

創建hive表：

create table table_name(
id string,
name string,
age string
)
row format serde
'org.apache.hadoop.hive.serde2.OpenCSVSerde'
with
SERDEPROPERTIES
("separatorChar"=",","quotechar"="\"")
STORED AS TEXTFILE;

 

導入數據：

load data local inpath '/home/kyang/table_name.csv' overwrite into table table_name;

 

將表轉換成ORC表：

create table table_name_orc(
id string, name string, age string )row format delimited fields terminated by "\t" STORED AS ORC

insert overwrite table table_name_orc select * from table_name
