Github user juliuszsompolski commented on the issue: https://github.com/apache/spark/pull/23152 This reproes it: ``` sql("create table all_null (attr1 int, attr2 int)") sql("insert into all_null values (null, null)") sql("analyze table all_null compute statistics for columns attr1, attr2") // check if the stats can be calculated without Cast exception. sql("select * from all_null where attr1 < attr2").queryExecution.stringWithStats ``` Could we piggy back this fix here? Sorry for posting last minute after lgtm.
