獲取錯誤區域名稱[us-west-1]無效[Kinesis流與spark整合]

Question

我已經設置了spark並嘗試使用python示例運行spark submit命令， 這里可以找到wordcount

以下是我為spark提交運行的命令： -

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]

我得到的錯誤如下： -

Traceback (most recent call last):
  File "/Users/amitdhawan/Downloads/kinesis_wordcount_asl.py", line 76, in <module>

不確定為什么我的區域無效，因為我已經確保我的Kinesis流和應用程序存在於aws-console的us-west-1中。

編輯：-

現在我在運行kinesis流的下面命令中得到錯誤

bin/run-example streaming.KinesisWordProducerASL streamname https://kinesis.us-west-1.amazonaws.com 1000 10

錯誤是： -

java.lang.ClassNotFoundException: org.apache.spark.examples.streaming.KinesisWordProducerASL

不知道我怎么能注冊這個課程。 我還在spark submit命令中提供了--class param，但這也沒有用。

Answer 1

使用以下命令解決了它： -

bin/spark-submit --packages org.apache.spark:spark-streaming-kinesis-asl_2.11:2.4.0  /Users/amitdhawan/Downloads/kinesis_wordcount_asl.py appname streamname https://kinesis.us-west-1.amazonaws.com us-west-1

觀察方括號被刪除，並將scala從2.12降級到2.11
