Maybe it just fails in my env, you can resubmit as-is for QA. In any case,
patches cannot be committed without +1 from QA. The vote [~hagleitn] was

> Recent development in Druid introduced new semantic of null handling
> [here|https://github.com/b-slim/druid/commit/219e77aeac9b07dc20dd9ab2dd537f3f17498346]
> Based on those changes when need to honer push down of expressions with is
> null/ is not null predicates.
> The prosed fix overrides the mapping of Calcite Function to Druid Expression
> to much the correct semantic.
