------------------------------------
Epic Link: IMPALA-12877
> Show the list of UDFs used in a query in the query profile
> ----------------------------------------------------------
>
> Key: IMPALA-12892
> URL: https://issues.apache.org/jira/browse/IMPALA-12892
> Project: IMPALA
> Issue Type: New Feature
> Reporter: Quanlong Huang
> Priority: Major
> Labels: observability, supportability
>
> When debugging JVM memory issues of impalads, we want to know if there are
> any Java UDFs contribute to that. It'd be helpful to show the list of UDFs
> that are used in a query in the query profile.
> On the other hand, Java UDFs are usually low performant comparing to native
> UDFs. We can show a warning in the profile saying Java UDFs are used.
