Herman van Hovell commented on SPARK-19518:
-------------------------------------------
Spark SQL has its own parser as of Spark 2.0. We currently don't support
{{IGNORE NULLS}} during parsing. It should be trivial to add though.
> IGNORE NULLS in first_value / last_value should be supported in SQL statements
