Problem with "only_full_group_by"

I try to run a ETL file, but i receive the error below:

The problem is, i disabled the mode on MySQL:

mysql> select @@sql_mode;
| @@sql_mode |
| |
1 row in set (0.00 sec)

in my.cnf to

Restart the MySQL, and the same error occur, how can i solve this? It’s a MySQL problem? Or ETL (Spoon/Pentaho) have some problem?

Thanks so much!
