--------------------------------
Summary: How can I create a User-defined analytic function?
Key: IMPALA-7849
URL: https://issues.apache.org/jira/browse/IMPALA-7849
Project: IMPALA
Issue Type: Improvement
Components: Clients, Frontend
Affects Versions: Impala 3.0
Reporter: zhangjun
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?
