------------------------------------
Assignee: Zhenhua Wang
> Avoid to fail twice in function lookup
> --------------------------------------
>
> Key: SPARK-30339
> URL: https://issues.apache.org/jira/browse/SPARK-30339
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.5, 3.0.0
> Reporter: Zhenhua Wang
> Assignee: Zhenhua Wang
> Priority: Minor
>
> Currently if function lookup fails, spark will give it a second change by
> casting decimal type to double type. But for cases where decimal type doesn't
> exist, it's meaningless to lookup again and causes extra cost like
> unnecessary metastore access. We should throw exceptions directly in these
> cases.
