--------------------------------------
Summary: 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: Daniel Barclay (Drill)
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).
