> Key: SPARK-13839
> URL: https://issues.apache.org/jira/browse/SPARK-13839
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Liang-Chi Hsieh
>
> After #11585, we filter out the rows early if it have null value. So we can
> only evaluate the inputs used in these filtering before this plan. The
> evaluation of other inputs can be deferred after the filtering done.
> Besides, currently we check IsNotNull(a) to find the attributes needed to
> filter out null values. However, the expression IsNotNull(Cast(a, dt)) will
> not be checked by this. We should add pattern to find this.
