Oozie4.2.0 解压之后的源码只有十几兆，但是依赖很多Jar，
1：将pom.xml中的 镜像注释掉
2：编译生成Java doc报错

解决：注意
1：将meven-javadoc-plugin 版本升级到3.x之后，不然下面的参数 -Xdoclint:none 不会生效
将内容贴出来：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>3.0.1</version>
<configuration>
<failOnError>false</failOnError>
<doclint>none</doclint>
</configuration>
</plugin>
3：oozie4.2.0 Bug 在 4.3.0版本以后修复
参见 https://issues.apache.org/jira/browse/OOZIE-2305

4： Openjpa maven plugin error
解决办法参考 https://stackoverflow.com/questions/3685113/openjpa-maven-plugin-error
增加蓝色部分配置
5：在编译 Core项目时 Test报错
解决办法： bin/mkdistro.sh -DskipTests 加上 _Dskip Tests 可以跳过检查
其他关于Hadoop，Spark版本在pom.xml中对应的修改
