Hive源碼編譯註意事項

一、指定Hadoop版本

如果不明確指定引用Hadoop版本會在編譯途中產生找不到Hadoop相關依賴class錯誤

mvn clean install -DskipTests -Phadoop-2

二、關於部分引用JAR找不到問題

雖然這個錯誤不會影響到整個編譯的正常執行，但是對於報錯還是讓人很不爽

錯誤

org.apache.maven.project.ProjectBuildingException: Error resolving project artifact: Failure to transfer org.pentaho:pentaho-aggdesigner-algorithm:pom:5.1.5-jhyde from https://repository.cloudera.com/content/repositories/snapshots was cached in the local repository, resolution will not be reattempted until the update interval of cdh.snapshots.repo has elapsed or updates are forced.

解決辦法

添加pentaho的reposity源

 <repository>
       <id>pentaho-omni</id>
       <url>http://repository.pentaho.org/content/groups/omni</url>
       <releases>
         <enabled>true</enabled>
       </releases>
       <snapshots>
         <enabled>false</enabled>
       </snapshots>
    </repository>

三、關於網速慢問題

這個很好解決。因爲所有的東西都在牆外，所以只需要添加一個牆內地址即可（但並不是所有用到JAR都在牆內有）

<repositories>
        <repository>
            <id>nexus</id>
            <name>local private nexus</name>
            <url>http://maven.oschina.net/content/groups/public/</url>
            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>nexus</id>
            <name>local private nexus</name>
            <url>http://maven.oschina.net/content/groups/public/</url>
            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </pluginRepository>
    </pluginRepositories>
