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。

  1. <properties>
  2. <hadoop.version>1.0.4</hadoop.version>
  3. </properties>
  5. <!-- Apache Hadoop Core -->
  6.     <dependency>
  7.         <groupId>org.apache.hadoop</groupId>
  8.         <artifactId>hadoop-client</artifactId>
  9.         <version>${hadoop.version}</version>
  10.     </dependency>
  12.     <dependency>
  13.         <groupId>org.apache.hadoop</groupId>
  14.         <artifactId>hadoop-core</artifactId>
  15.         <version>${hadoop.version}</version>
  16.     </dependency>
  18.     <dependency>
  19.         <groupId>org.apache.hadoop</groupId>
  20.         <artifactId>hadoop-examples</artifactId>

  22.     </dependency>
  24.     <dependency>
  25.         <groupId>org.apache.hadoop</groupId>

您可以使用下面的pom为项目解析hadoop依赖项。

  1. <repositories>
  2.     <repository>
  3.         <id>cloudera</id>
  4.         <url>https://repository.cloudera.com/artifactory/cloudera-repos/</url>
  5.     </repository>
  6. </repositories>
  7. <properties>
  8.     <hadoop-version>2.0.0-cdh4.2.0</hadoop-version>
  9. </properties>
  10. <dependencies>
  11.     <dependency>
