RowNumber in HiveContext returns null or negative values

[Saif.A.Ellafi]

Hi all, would this be a bug??

        val ws = Window.
            partitionBy("clrty_id").
            orderBy("filemonth_dtt")

        val nm = "repeatMe"
        df.select(df.col("*"), rowNumber().over(ws).cast("int").as(nm))

        
stacked_data.filter(stacked_data("repeatMe").isNotNull).orderBy("repeatMe").take(50).foreach(println(_))

--->
