I have created a table:
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/';
I then got a success from this query:
INSERT into TABLE sampleout select *, 0 as calculatedcolumn from sampletable
sampleout
is the same as sampletable
except for the extra column calculatedcolumn
. After the successful insert, I opened the blob storage and opened the text file to verify the data is in the specified textfile location.
However...
select * from sampleout limit 10
returns the following error:

OK

how is it that I can successfully insert, but cannot select from the table? Note that the error shows '/hive' added to the textfile location specified in the create.
