> For example, if array is used (where the lower and upper bounds for its column batch
are {{null}})), it looks wrongly filtering all data out:
> {code}
> scala> import org.apache.spark.sql.functions
> import org.apache.spark.sql.functions
> scala> val df = Seq(Array("a", "b"), Array("c", "d")).toDF("arrayCol")
> df: org.apache.spark.sql.DataFrame = [arrayCol: array<string>]
> scala> df.filter(df.col("arrayCol").eqNullSafe(functions.array(functions.lit("a"),
functions.lit("b")))).show()
> +--------+
> |arrayCol|
> +--------+
> |  [a, b]|
> +--------+
> scala> df.cache().filter(df.col("arrayCol").eqNullSafe(functions.array(functions.lit("a"),
functions.lit("b")))).show()
> +--------+
> |arrayCol|
> +--------+
> +--------+
> {code}
