Hadoop maven依赖性错误 - 找不到hadoop类 [英] Hadoop maven dependency error - hadoop classes are not found

问题描述

尽管我将以下依赖项导入到我的pom中，但未导入相关的Hadoop类（org.apache.hadoop。*）。

Despite I import following dependencies into my pom, related Hadoop classes (org.apache.hadoop.*) are not imported.

<properties>
<hadoop.version>1.0.4</hadoop.version>
</properties>

        <version>${hadoop.version}</version>
    </dependency>
