How do I output the results of a HiveQL query to CSV?

Question

we would like to put the results of a Hive query to a CSV file. I thought the command should look like this:

insert overwrite directory \'/home/output.csv\'          


        

Answer 1

This is most csv friendly way I found to output the results of HiveQL.
You don't need any grep or sed commands to format the data, instead hive supports it, just need to add extra tag of outputformat.

hive --outputformat=csv2 -e 'select * from  limit 20' > /path/toStore/data/results.csv
