> Key: DRILL-2558
> URL: https://issues.apache.org/jira/browse/DRILL-2558
> Project: Apache Drill
> Issue Type: Bug
> Components: Functions - Drill
> Affects Versions: 0.8.0
> Reporter: Victoria Markman
> Assignee: Daniel Barclay (Drill)
>
> Drill tries to do implicit cast during runtime, and we agreed that if particular cast is not implemented run time exception is fine for now.
> However, it feels weird to get four of them at the same time.
> I think we should throw exception on the first incompatibility and stop processing rest of the arguments.
