我已从spark DataFrame中读取此行：
scala> val t = df.take(99)
scala> t(0)(0)
res69: Any = [2,null,WrappedArray([20789823,null,0.0,null,1490788977,1], [50115961,null,0.0,null,1490788977,1], [20787723,null,0.0,null,1490788977,1], [20796254,null,0.0,null,1490788977,1]),null,1488196976]
但遗憾的是，我不知道如何在Any中访问包装数组。
虽然我可以将它转换为String并解析输出字符串，但我正在寻找正确的方法来访问数组。
