It seems `df.createTempView` is a use case of `NullType` with `in-memory`. During resolve failed test, I find many place use `create temp view as select null` or `df.createTempView`. The result is, we can't or hard to test anything about `NullType` if we forbid create view with it. e.g., * test function/udf that accept null * test sizeInBytes in memory that include null column I'm not confident to remove all that test. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
