HADOOP HIVE-是否有用于设置csv输出的命令

Question

Is there a command line in HIVE that can be used to define the format of the output file to CSV?

Something similar to the below example?

set hive.resultset.use.unique.column.names=false;

EDIT - Added the following for further context 12/18 .

A terminal window I'm using has predefined settings for the command line when it runs an 'export' through a script. The following is it's commands:

set hive.metastore.warehouse.dir=/idn/home/user;
set mapred.job.queue.name=root.gmis;
set hive.exec.scratchdir=/axp/hivescratch/user;
set hive.resultset.use.unique.column.names=false;
set hive.cli.print.header=true;
set hive.groupby.orderby.position.alias=true;

Is there another command I could add versus the lengthy strings per below? I'm using in the other hive terminal the following; but it's SQL is different(?).

cloak-hive -e "INSERT OVERWRITE LOCAL DIRECTORY '/adshome/user/VS_PMD' ROW FORMAT DELIMITED FIELDS TERMINATED BY ','

Answer 1

On Apache documentation, https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML#LanguageManualDML-Writingdataintothefilesystemfromqueries

Standard syntax:

 INSERT OVERWRITE [LOCAL] DIRECTORY directory1 [ROW FORMAT row_format] [STORED AS file_format] SELECT ... FROM ... 

INSERT OVERWRITE LOCAL DIRECTORY directory1 
ROW FORMAT DELIMITED 
STORED AS TEXTFILE 
SELECT ... FROM ...;

Maybe some work would be needed on ROW FORMAT to achieve expected result. Please note also that LOCAL value refers to local filesystem.

You can mention the out put file format to csv refer the following example command. Note that it's same for beeline and hive

beeline -u jdbc:hive2://localhost:10000/default --silent=true --outputformat=csv2 -e "select * from sample_07 limit 10" > out.txt
