Question

我正在尝试设置apache流。在下面的pom.xml中。我何时加入

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

pom文件出错，说：在此行找到多个注释： - 未转让org.glassfish.hk2：hk2-utils：jar：2.4.0-b34

请有人帮我解决这个问题。这是偶然的。

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：

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