Browse Source 
Introduced UDF and stored prodecure.
usage:

set columnstore_s3_key='<s3_key>';
set columnstore_s3_secret='<s3_secret>';
set columnstore_s3_region='region';

and then use UDF
select columnstore_dataload("<tablename>", "<filename>", "<bucket>", "<db_name>");
for UDF db_name can be ommited, then current connection db will be used

or stored function
call calpontsys.columnstore_load_from_s3("<tablename>", "<filename>", "<bucket>", "<db_name>");
