我总是收到以下错误。有人可以帮帮我吗？

org.apache.spark.Logging在Spark 1.5.2或更低版本中可用。它不在2.0.0中。请按以下方式更改版本

    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-streaming_2.11</artifactId>
        <version>1.5.2</version>
    </dependency>

    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-core_2.10</artifactId>
        <version>1.5.2</version>
    </dependency>

    <dependency>
        <groupId>org.apache.spark</groupId>

    </dependency>

答案 1 :(得分：8)

错误是因为您使用Spark 2.0库和Spark 1.6的连接器（它查找Spark 1.6日志记录类。使用2.0.5版本的连接器。

答案 2 :(得分：3)

这是因为自1.5.2以来缺少org.apache.spark.Logging类，就像每个人都说的那样。 （只有org.apache.spark.internal.Logging存在于更高版本中......）

但似乎没有针对maven的解决方案可以解决这种依赖关系，所以我只是尝试手动将这个类添加到lib。这是解决问题的方法：

  1. 将scala org.apache.spark.internal.Logging打包到公共jar中。或者从https://raw.githubusercontent.com/swordsmanliu/SparkStreamingHbase/master/lib/spark-core_2.11-1.5.2.logging.jar下载（感谢此主机。）

  2. 将jar移动到spark cluster的jars目录中。

  3. 再次提交您的项目，希望它能为您提供帮助。

答案 3 :(得分：2)

我通过更改上面提到的jar来获得解决方案。

最初，我正在为spark-kafka-streaming降级jar：

<dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-streaming-kafka-0-8_2.11</artifactId>
        <version>2.1.1</version></dependency>

我还删除了我从spark和kafka jar库外部添加的多个sl4j-log4j.jars和log4j.jars。

答案 4 :(得分：1)

下载spark-core_2.11-1.5.2.logging.jar并使用--jar选项

spark-submit --class com.SentimentTwiteer --packages＆＃34; org.apache.spark：spark-streaming-twitter_2.11：1.6.3＆＃34; --jars /root/Desktop/spark-core_2.11-1.5.2.logging.jar /root/Desktop/SentimentTwiteer.jar consumerKey consumerSecret accessToken accessTokenSecret yoursearchTag

可能导致此问题的一个原因是 lib和类冲突。 我遇到了这个问题并使用一些 maven排除

下载jar并在spark-submit中使用--jars，为我工作 spark-submit --class com.SentimentTwiteer --packages“org.apache.spark：spark-streaming-twitter_2.11：1.6.3”--jars /root/Desktop/spark-core_2.11-1.5.2.logging .jar /root/Desktop/SentimentTwiteer.jar XX XX XX XX

答案 8 :(得分：0)

下载下面的Jar并将其放入您的库中，它将按预期工作。

https://raw.githubusercontent.com/swordsmanliu/SparkStreamingHbase/master/lib/spark-core_2.11-1.5.2.logging.jar

答案 9 :(得分：0)

如果您使用的是IntelliJ，只需选中“包括具有提供的作用域的依赖项”框，即可为您解决该问题，而无需弄乱pom或手动下载文件。

答案 10 :(得分：-1)

在您的依赖关系jar列表中缺少日志记录Jar。尝试下载＆＃34; spark-core_2.11-1.5.2.logging＆＃34;来自mvn存储库的jar，然后将它作为外部jar添加到你的spark项目中，你不会得到＆＃34; java.lang.NoClassDefFoundError：org / apache / spark / Logging＆＃34;错误。 基于scala版本，您可以下载jar {2.10,2.11等}。
