设置 apache spark 时 Maven pom.xml 出错

Question

我正在尝试设置 apache 流式传输。在下面pom.xml。当我添加

    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-core_2.10</artifactId>
        <version>2.1.0</version>
    </dependency>

pom 文件出现错误，提示：在此行发现多个注释： - 传输失败 org.glassfish.hk2:hk2-utils:jar:2.4.0-b34

请有人帮助我解决此问题 issue.Thans adavnce

您需要使用相同版本的 spark-core 和 spark-streaming-kafka。请尝试将 spark-streaming-kafka 依赖项更改为此：

<dependency>
    <groupId>org.apache.spark</groupId>
    <artifactId>spark-streaming-kafka-0-8_2.10</artifactId>
    <version>2.1.0</version>
</dependency>
