--------------------------------------
Assignee: Jason Altekruse
> Add appropriate constant flag on UDF inputs that are used in the setup method
> -----------------------------------------------------------------------------
>
> Key: DRILL-2360
> URL: https://issues.apache.org/jira/browse/DRILL-2360
> Project: Apache Drill
> Issue Type: Bug
> Components: Functions - Drill
> Reporter: Jason Altekruse
> Assignee: Jason Altekruse
> Fix For: Future
>
>
> A number of UDFs do not include the appropriate flag to declare them as
> constants when the should be. Any input used in the setup method should
> include a constant flag in the @Param annotation for it (this allows us to
> detect and throw a helpful error message if they are used incorrectly). A
> correct example can be found in StringFunctions.RegexpReplace, an incorrect
> example can be found in GFloat8ToChar (available after running the freemarker
> generation that is a part of the default mvn install build).
