PARQUET File getting created as empty file

[#1]

Hi Team,

Am trying to create a PARQUET file through the below

INSERT OVERWRITE DIRECTORY '/data/dev1/consumption/crm'

STORED AS PARQUET

SELECT * FROM PROV_CUST;

However, I could see that the file is always empty even when there are data in the table.

Could someone please assist

Thanks

what do you have in this file - /data/dev1/consumption/crm

sorry i am not quite getting your requirement ? if i understand clearly you want to load the data to the table with parquet format ?

Requirement is to create a parquet file and send it to downstream.

Issue is that parquet file is always getting created as empty file even when there is data in "select * from prov_cust" table.
