I can create a UDAF with the "create aggregate function ....", but when I use this aggregate function for the analysis function, such as sql : select hour,my_udaf(id) over (partition by hour) from mytable ,it reports the following error.
ERROR: AnalysisException: Aggregate function 'my_udaf(id)' not supported with OVER clause.
How can I create the analytic function? Is this an imperfect function, or is it not designed to provide this function for some reason?
