Question

使用kafka_2.11-0.9.0.0和zookeeper-3.4.9。

我已经启动了zookeeper服务以及生产者和消费者。但是，当我运行spark submit命令时，它会抛出错误。我使用下面的命令提交火花作业：

spark-submit --packages org.apache.spark:spark-streaming-kafka_2.11:1.5.0 /usr/local/spark/examples/src/main/python/streaming/kafka_wordcount.py localhost:2181 Hello-Kafka

我在日志中遇到错误。

这是我得到的日志：

任何想法??

Answer 1

看起来你正在尝试使用spark 2.X和来自spark 1.5 ...

的库

修复您的--packages选项，传递有效的库版本。您可以直接从maven repository获取可能的版本。

使用python进行火花流时获取错误？
