我创建了一个表:
DROP TABLE IF EXISTS sampleout;
CREATE EXTERNAL TABLE sampleout(
id bigint,
LNG FLOAT,
LAT FLOAT,
GMTDateTime TIMESTAMP,
calculatedcolumn FLOAT
)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ','
STORED AS TEXTFILE LOCATION 'wasb://sampleout@xxxxxx.blob.core.windows.net/';
然后我从这个查询中获得了成功:
INSERT into TABLE sampleout select *, 0 as calculatedcolumn from sampletable
sampleout
与sampletable
相同,但额外的列calculatedcolumn
除外。成功插入后,我打开blob存储并打开文本文件以验证数据是否在指定的文本文件位置。
...然而
select * from sampleout limit 10
返回以下错误:

我怎样才能成功插入,但无法从表中选择?请注意,错误显示' / hive'添加到create。
中指定的文本文件位置答案 0 :(得分:0)
基本上,不要将TEXTFILE LOCATION放在根目录下。即使它是blob存储(没有真正的文件夹),HDFS或其他东西所需的结构也希望你在该位置使用至少一个子文件夹。
从
移动wasb://sampleout@xxxxxx.blob.core.windows.net/
到
wasb://sampleout@xxxxxx.blob.core.windows.net/somefolder/
