我试图将Array [Row]转换为Array [Int]，但徒劳。感谢一些帮助
scala> res17(0).toInt
<console>:30: error: value toInt is not a member of org.apache.spark.sql.Row
res17(0).toInt
^
scala> res17(0)
res28: org.apache.spark.sql.Row = [1,0]
scala> res17(0).toArray
<console>:30: error: value toArray is not a member of org.apache.spark.sql.Row
res17(0).toArray
^
scala> res17
res30: Array[org.apache.spark.sql.Row] = Array([1,0])
只要map有getInt：
val rows: Array[Row] = ???
rows.map(_.getInt(0))
