查看Spark与Hadoop等其他组件的兼容版本

安装与Spark相关的其他组件的时候，例如JDK，Hadoop，Yarn，Hive，Kafka等，要考虑到这些组件和Spark的版本兼容关系。这个对应关系可以在Spark源代码的pom.xml文件中查看。

一、 下载Spark源代码

打开网址https://github.com/apache/spark，例如选择v2.4.0-rc5版本，再点击“Clone or download”按钮，点击下方的“Download ZIP”进行下载。

二、查看pom.xml文件
将下载的源代码压缩包解压后，打开里面的pom.xml文件，查看properties标签内各配置项，里面有列出其他组件的兼容版本信息，例如<hadoop.version>2.6.5</hadoop.version>表示hadoop版本为2.6.5。如下：
