在Eclipse上建立hadoop2.2.0/hadoop2.4.0源代码阅读环境

1.安装依赖的包:

yum install gcc-c++ g++ autoconf automake libtool cmake zlib1g-dev pkg-config libssl-dev

2. 安装protobuf 2.5.0,

首先去google的网站上下载protobuf源代码,解压并切换到root用户执行如下命令:

./configure

如果中间发生错误,说明有些依赖包并为安装,

an error occured because dependency is not met
the error is cleaned

把所须依赖都安装好之后,执行:

./make
./make install

3.编译Hadoop源代码

首先下载hadoop-2.2.0的源代码,解压。

2.1. 切换到源代码目录,执行:

mvn install -DskipTests -Dhttp.proxyHost=proxy01.cd.intel.com -Dhttp.proxyPort=

黄色部分作用为设置代理。由于本人的编译环境在公司内网,所以需要设置代理

发现如下错误:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.:testCompile (default-testCompile) on project hadoop-auth: Compilation failure: Compilation failure:
[ERROR] /home/hduser/hadoop-2.2.-src/hadoop-common-project/hadoop-auth/src/test/java/org/apache/hadoop/security/authentication/client/AuthenticatorTestCase.java:[,] error: cannot access AbstractLifeCycle

[ERROR] -> [Help ]

需要修改源码下边的hadoop-common-project/hadoop-auth/pom.xml,黄色部分为新增代码

    <dependency>
      <groupId>org.mortbay.jetty</groupId>
      <artifactId>jetty</artifactId>
      <scope>test</scope>
    </dependency>
  <dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-util</artifactId>
<scope>test</scope>
</dependency>

重新执行,顺利通过

2.2. 生成eclipse项目环境:

 mvn eclipse:eclipse -DskipTests -Dhttp.proxyHost=proxy01.cd.intel.com -Dhttp.proxyPort=

2.3. 打开eclipse,导入源代码目录下的项目.
