我有一个未分区的表
create table tabUn
(
col1 string,
col2 int
)
可以说它有一些数据。接下来,我创建了一个分区表
CREATE EXTERNAL TABLE tabPart
(
col1 string,
col2 int
)
PARTITIONED BY (col_date string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t'
STORED AS TEXTFILE
LOCATION '/path/to/table';
最后,我尝试将数据复制到
set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;
INSERT OVERWRITE TABLE tabPart PARTITION(data_date='2018-10-01')
SELECT
(
col1,
col2,
'2018-10-01' as col_date
) select * FROM tabUn;
但出现以下错误
失败:NullPointerException为空
我在做什么错了?
答案 0 :(得分:1)
您的选择语句似乎不正确。
INSERT OVERWRITE TABLE tabPart PARTITION (data_date='2018-10-01')
SELECT col1,col2,'2018-10-01' as col_date from tabUn;
