Datafusion aggregation functions last_value and first_value are not working in Ballista remote mode. Please see my query below
select sum(a) ,first_value(location_changed ) ,node_id from t1 group by node_id
This query produces a NotImplemented Error at the scheduler side and hangs the client side without any error.
Note: I am running in macOS, using the latest version of the Ballista and Datafusion 26
