Hi @leanken !
I'd ask maybe Is the PR description for `spark.sql("select
element_at(array(3, 2, 1), 0)").printSchema()` correct?
I ran the reproducers in the PR description and it shows a different result
in the master branch.
```scala
scala> spark.sql("select element_at(array(3, 2, 1), 0)").printSchema()
root
|-- element_at(array(3, 2, 1), 0): integer (nullable = false)
```
It returned `nullable = false`, but in the PR description says that `true`
is expected.
Or could you please correct me if I missed something??
Thanks :)
