> Dynamic partition will fail when both '' and null values are taken as dynamic partition values simultaneously.
> For example, the test bellow will fail.
> test("Null and '' values should not cause dynamic partition failure of string types") {
> withTable("t1", "t2")
> { spark.range(3).write.saveAsTable("t1") spark.sql("select id, cast(case when id = 1 then '' else null end as string) as p" + " from t1").write.partitionBy("p").saveAsTable("t2") checkAnswer(spark.table("t2").sort("id"), Seq(Row(0, null), Row(1, null), Row(2, null))) }
