try using List as parameter:
尝试使用 List 作为参数:
sc.parallelize(List(line)).collect()
it returns
它返回
res1: Array[String] = Array(hello,world)
回答by Dhruv
The below code works fine in Python
下面的代码在 Python 中运行良好
sc.parallelize([line]).collect()
['Hello, world']
sc.parallelize([line]).collect()
['你好,世界']
Here we are passing the parameter "line" as a list.
这里我们将参数“line”作为列表传递。
