Hadoop 源码编译导出

https://svn.apache.org/repos/asf/hadoop/common/branches/branch-trunk-win/BUILDING.txt

http://www.srccodes.com/p/article/38/build-install-configure-run-apache-hadoop-2.2.0-microsoft-windows-os

 $ mvn package -Pdist -DskipTests -Dtar 

错误：

1.错误: 类重复: org.apache.hadoop.ipc.protobuf.TestProtos....

原因是在导入eclipse是手动生成的文件和hadoop的maven自动配置出现冲突。

将手动添加的部分删除。

可在源码同级建立临时文件夹执行如下bat

mv ../hadoop-2.4.0-src/hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/ipc/protobuf/TestProtos.java ./

mv ../hadoop-2.4.0-src/hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/io/serializer/avro/AvroRecord.java ./

mv ../hadoop-2.4.0-src/hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/ipc/protobuf/TestRpcServiceProtos.java ./

move out
