Bruce Robbins created SPARK-45106:
-------------------------------------
Summary: percentile_cont gets internal error when user input
fails runtime replacement's input type check
Key: SPARK-45106
URL: https://issues.apache.org/jira/browse/SPARK-45106
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.4.1, 3.5.0, 4.0.0
Reporter: Bruce Robbins
This query throws an internal error rather than producing a useful error
message:
{noformat}
select percentile_cont(b) WITHIN GROUP (ORDER BY a DESC) as x
from (values (12, 0.25), (13, 0.25), (22, 0.25)) as (a, b);
[INTERNAL_ERROR] Cannot resolve the runtime replaceable expression
"percentile_cont(a, b)". The replacement is unresolved: "percentile(a, b, 1)".
org.apache.spark.SparkException: [INTERNAL_ERROR] Cannot resolve the runtime
replaceable expression "percentile_cont(a, b)". The replacement is unresolved:
"percentile(a, b, 1)".

It should instead inform the user that the input expression must be foldable.
{{PercentileCont}} does not check the user's input. If the runtime replacement
(an instance of {{Percentile}}) rejects the user's input, the runtime
replacement ends up unresolved.
