先是在的 hive 命令行建的表,胜利导入了,然而 impala 客户端查不到,而后刷新了元数据(invalidate metadata 表名)
impala 报错不反对 org.apache.hadoop.hive.serde2.OpenCSVSerde
而后就选了第二种办法(留神分隔符)
一、建表
1.
create table if not exists test.product_browsing (
user_id STRING,
phone STRING,
goods_id STRING,
goods_name STRING,
view_date STRING,
view_time STRING
) row format serde
'org.apache.hadoop.hive.serde2.OpenCSVSerde'
with
SERDEPROPERTIES
("separatorChar"=",","quotechar"="\"")
STORED AS TEXTFILE;
2.
create table if not exists Impala.test.product_browsing (
user_id STRING,
phone STRING,
goods_id STRING,
goods_name STRING,
view_date STRING,
view_time STRING
) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS TEXTFILE;
二、加载数据命令
load data local inpath '/home/data.csv' overwrite into table test.product_browsing;
