【甘道夫】CDH5.2的Maven依赖

之前一直结合Maven开发Hadoop2.2.0的程序。环境换成CDH5.2后报错，发现是Maven依赖库的问题。

之前一直使用

http://mvnrepository.com/

查找maven依赖。但这类站点仅仅能查到通用的maven依赖，没有包括CDH依赖。还好Cloudera提供了CDH的依赖：

http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cdh_vd_cdh5_maven_repo.html

简言之，往pom文件增加下面两部分内容就可以：

1.指向cloudera的库

    <repositories>

        <repository>

            <id>cloudera</id>

            <url>https://repository.cloudera.com/artifactory/cloudera-repos/</url>

        </repository>

    </repositories>  

2.CDH相关依赖，比方

        <dependency>

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

            <artifactId>hadoop-common</artifactId>

            <version>2.5.0-cdh5.2.0</version>

        </dependency>

        <dependency>

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

            <artifactId>hadoop-hdfs</artifactId>

            <version>2.5.0-cdh5.2.0</version>

        </dependency>

        

        <dependency>

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

            <artifactId>hadoop-maven-plugins</artifactId>

            <version>2.5.0-cdh5.2.0</version>

        </dependency>

        

        <dependency>

            <groupId>org.apache.hbase</groupId>

            <artifactId>hbase-client</artifactId>

            <version>0.98.6-cdh5.2.0</version>

        </dependency>  

很多其它的CDH依赖请查阅
