 Review comment:
   Could you please add checks similar to [`DrillFuncHolder`](https://github.com/apache/drill/blob/755529f3ac7ca77797f68b60e1d0713ad126e227/exec/java-exec/src/main/java/org/apache/drill/exec/expr/fn/DrillFuncHolder.java#L185) to ensure that the required variable should be injected, or even better - reformat code if possible to use common code for these two classes to inject variables in the same way?
