Hadoop 2.0 native lib build failed, Hadoop 2.0 本地库编译失败

Trevor Robinson created HADOOP-8370:
---------------------------------------

Summary: Native build failure: javah: class file for org.apache.hadoop.classification.InterfaceAudience not found
Key: HADOOP-8370
URL: https://issues.apache.org/jira/browse/HADOOP-8370
Project: Hadoop Common
Issue Type: Bug
Components: native
Affects Versions: 0.23.1

编译hadoop本地库出现问题，报错

Failed to execute goalorg.codehaus.mojo:native-maven-plugin:1.0-alpha-7:javah (default) onproject hadoop-common: Error running javah command: Error executing commandline

找了好长时间最后终于找到解决方法。

The fix for me was to changing the scope of hadoop-annotations from
"provided" to "compile" in pom.xml:

<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-annotations</artifactId>
<scope>compile</scope>
</dependency>

For some reason, it was the only dependency with scope "provided".

解决方法：

vi ./hadoop-common-project/hadoop-auth/pom.xml
vi ./hadoop-common-project/hadoop-common/pom.xml 

<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-annotations</artifactId>
<scope>compile</scope>
</dependency>

将节点hadoop-annotations的值由provide 改成compile
