【问题描述】：
我已经设置了 spark 并尝试使用 python 示例运行 spark 提交命令以查找字数 here
下面是我为 spark submit 运行的命令：-
bin/spark-submit --packages org.apache.spark:spark-streaming-kinesis-asl_2.12:2.4.0 /Users/amitdhawan/Downloads/kinesis_wordcount_asl.py [appname] [streamname] [https://kinesis.us-west-1.amazonaws.com] [us-west-1]
我得到的错误如下：-
Traceback (most recent call last):

不知道为什么我从 aws-console 确保我的 Kinesis 流和应用程序存在于 us-west-1 中的区域无效。
编辑：-
现在我在运行 kinesis 流的命令中遇到错误
bin/run-example streaming.KinesisWordProducerASL streamname https://kinesis.us-west-1.amazonaws.com 1000 10
错误是：-
java.lang.ClassNotFoundException: org.apache.spark.examples.streaming.KinesisWordProducerASL

不知道如何注册这个课程。我还在 spark submit 命令中提供了 --class 参数，但这也不起作用。
