Spark 1.4缺少Kafka库

Question

我正在尝试运行一个在spark 1.3.1中完美运行的Python spark脚本。我已经下载了火花1.4并试图运行脚本，但它一直在说

在类路径中找不到Spark Streaming的Kafka库。请尝试以下方法之一。

1. 在spark-submit命令中包含Kafka库及其依赖项 $ bin/spark-submit --packages org.apache.spark:spark-streaming-kafka:1.4.0 ...
2. 从Maven Central http://search.maven.org/下载工件的JAR，Group Id = org.apache.spark，Artifact Id = spark-streaming-kafka-assembly，Version = 1.4.0。然后，在spark-submit命令中包含jar作为 $ bin/spark-submit --jars <spark-streaming-kafka-assembly.jar> ...

我在提交命令中明确引用了jar，并将jar添加为

/opt/spark/spark-1.4.0-bin-hadoop2.6/bin/spark-submit --jars spark-streaming_2.10-1.4.0.jar,spark-core_2.10-1.4.0.jar,spark-streaming-kafka-assembly_2.10-1.4.0.jar,kafka_2.10-0.8.2.1.jar,kafka-clients-0.8.2.1.jar,spark-streaming-kafka-assembly_2.10-1.4.0.jar /root/SparkPySQLNew.py

它还表示它已经在应用程序启动时添加了它们，为什么它没有找到它们？

而且我知道我已经加载了它们，我从一个开始，然后最后将它们全部添加到最后。

Answer 1

我怀疑每个版本的火花确切的答案各不相同，但基于this HCC thread，以下似乎为其他人做了伎俩：

spark-submit --jars spark-assembly-1.5.2.2.3.4.7-4-hadoop2.7.1.2.3.4.7-4.jar,spark-streaming-kafka-assembly_2.10-1.6.1.jar 

乍一看，差异在于它有1个spark-streaming-kafka-assembly jar，而你提交的是2个。
