尽管我将以下依赖项导入到pom中，但是相关的hadoop类 (org.apache.hadoop.*) 不是进口的。

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

<!-- Apache Hadoop Core -->
    <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-client</artifactId>
        <version>${hadoop.version}</version>
    </dependency>

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

    </dependency>

您可以使用下面的pom为项目解析hadoop依赖项。

    <repository>
