Hadoop-2.4.0分布式安装手册

laozi888 2014-10-19 11:00:56

1. 前言

Hadoop-2.4.0的源码目录下有个BUILDING.txt文件，它介绍了如何在Linux和Windows下编译源代码，本文基本是遵照BUILDING.txt指示来操作的，这里再做一下简单的提炼。

第一次编译要求能够访问互联网，Hadoop的编译依赖非常多的东西，一定要保证机器可访问互联网，否则难逐一解决所有的编译问题，但第一次之后的编译则不用再下载了。
2. 安装依赖

在编译Hadoop 2.4.0源码之前，需要将下列几个依赖的东西安装好：

1) JDK 1.6或更新版本（本文使用JDK1.7，请不要安装JDK1.8版本，JDK1.8和Hadoop 2.4.0不匹配，编译Hadoop 2.4.0源码时会报很多错误）

2) Maven 3.0或更新版本

3) ProtocolBuffer 2.5.0

4) CMake 2.6或更新版本

5) Findbugs 1.3.9，可选的（本文编译时未安装）

在安装好之后，还需要设置一下环境变量，可以修改/etc/profile，也可以是修改~/.profile，增加如下内容：

export JAVA_HOME=/root/jdk

export CLASSPATH=$JAVA_HOME/lib/tools.jar

export PATH=$JAVA_HOME/bin:$PATH

export CMAKE_HOME=/root/cmake

export PATH=$CMAKE_HOME/bin:$PATH

export PROTOC_HOME=/root/protobuf

export PATH=$PROTOC_HOME/bin:$PATH

export MAVEN_HOME=/root/maven

export PATH=$MAVEN_HOME/bin:$PATH

本文以root用户在/root目录下进行安装，但实际可以选择非root用户及非/root目录进行安装。

2.1. 安装ProtocolBuffer

标准的automake编译安装方式：

1) cd /root

2) tar xzf protobuf-2.5.0.tar.gz

3) cd protobuf-2.5.0

4) ./conigure --prefix=/root/protobuf

5) make

6) make install
2.2. 安装CMake

1) cd /root

2) tar xzf cmake-2.8.12.2.tar.gz

3) cd cmake-2.8.12.2

4) ./bootstrap --prefix=/root/cmake

5) make

6) make install
2.3. 安装JDK

1) cd /root

2) tar xzf jdk-7u55-linux-x64.gz

3) cd jdk1.7.0_55

4) ln -s jdk1.7.0_55 jdk
2.4. 安装Maven

1) cd /root

2) tar xzf apache-maven-3.0.5-bin.tar.gz

3) ln -s apache-maven-3.0.5 maven
3. 编译Hadoop源代码

完成上述准备工作后，即可通过执行命令：mvn package -Pdist -DskipTests -Dtar，启动对Hadoop源代码的编译。请注意一定不要使用JDK1.8。

编译成功后，jar文件会放在target子目录下，可以在Hadoop源码目录下借用find命令搜索各个target子目录。

编译成功后，会生成Hadoop二进制安装包hadoop-2.4.0.tar.gz，放在源代码的hadoop-dist/target子目录下：

main:

[exec] $ tar cf hadoop-2.4.0.tar hadoop-2.4.0

[exec] $ gzip -f hadoop-2.4.0.tar

[exec]

附3：常见错误1) unexpected end tag: </ul>

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.8.1:jar (module-javadocs) on project hadoop-annotations: MavenReportException: Error while creating archive:

[ERROR] Exit code: 1 - /root/hadoop-2.4.0-src/hadoop-common-project/hadoop-annotations/src/main/java/org/apache/hadoop/classification/InterfaceStability.java:27: error: unexpected end tag: </ul>

[ERROR] * </ul>

[ERROR] ^

[ERROR]

[ERROR] Command line was: /root/jdk1.8.0/jre/../bin/javadoc @options @packages

原因是InterfaceStability.java中的注释问题：

解决办法，将JDK换成1.7版本，使用JDK1.8编译就会遇到上述问题，将</ul>行删除可以解决问题，但后续还会遇到类似的问题，所以不要使用JDK1.8编译Hadoop 2.4.0。
