你如何在 py4j 上使用 scala.collection.mutable.ArrayBuffer

Question

我一般会尝试消耗 SparkListenerJobStart object in Python, but the py4j bindings do not understand ArrayBuffers (or, I guess, scala.collection.Seqs）。做什么？

Answer 1

像这样转换对象：

list = [arrayBuffer.apply(i)
        for i in range(arrayBuffer.length())]

How do you consume a scala.collection.mutable.ArrayBuffer over py4j
