CentOS64位系统进行Hadoop2.3.0本地编译及完全分布式集群的部署

本文是在小编的博文《 基于Hadoop1.2.1完全分布式集群的部署 》的基础上写作的，所有硬件环境跟之前博文的硬件环境一模一样，因此本文不想再这方面费过多的口舌，关于hosts配置、JDK的安装和SSH互信.

本文主要讲述如何在CentOS64位操作系统下本地编译hadoop2.3.0的源码，并在此基础上进行3台虚拟主机间的hadoop集群的部署及对Hadoop1.X与Hadoop2.X的安装做简要的总结！

在官方所给的hadoop2.3.0的安装版压缩文件中存在一个巨大的坑，按照正常的集群搭建步骤总是卡在格式化NameNode上，其中的原因是官方压缩包里的libhadoop.so.1.0.0是32位的，也就是说如果在32位linux操作系统上不存在这样的问题；如果想要在64位的linux系统上安装hadoop2.3.0,必须将源码在本地编译一遍，如此才能从根本上解决问题，本文的目的也是帮助初学者很快地在本地编译源码并顺利进行基于Hadoop2.3.0 完全分布式集群的部署，废话不多说，自己接切入主题吧！

Let\'s Go !一、安装与编译有关的包（基于CentOS）svn

[root@localhost Downloads]# yum install svn autoconfautomake libtool cmake

[root@localhost Downloads]# yum install autoconfautomake libtool cmake ncurses-devel

[root@localhost Downloads]# yum install ncurses-devel openssl=devel

[root@localhost Downloads]# yum install openssl-devel gcc

[root@localhost Downloads]# yum install gcc* 二、安装maven 下载和解压maven

[root@localhost Desktop]# wget http://mirrors.hust.edu.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz [root@localhost Desktop]# tar xzvf apache-maven-3.3.9-bin.tar.gz 配置环境变量

[root@localhost grid]# ls -a . .gnome2 Public .. .gnome2_private .pulse .bash_history .gnote .pulse-cookie .bash_logout .gnupg .recently-used.xbel .bash_profile .gstreamer-0.10 release-2.3.0 .bashrc .gtk-bookmarks release-2.5.0 .cache .gvfs .spice-vdagent .config hadoop-2.7.3-src.tar.gz .ssh .dbus .ICEauthority .subversion Desktop .icons Templates .dmrc .imsettings.log .themes Documents .local .thumbnails Downloads .m2 Videos eclipse .mozilla .viminfo .eclipse Music workspace .esd_auth .nautilus .xinputrc .fontconfig .oracle_jre_usage .xsession-errors .gconf .p2 .xsession-errors.old .gconfd Pictures [root@localhost grid]# vi .bash_profile

配置JDK的路径：

# User specific environment and startup programs PATH=$PATH:$HOME/bin:/usr/local/apache-maven-3.3.9/bin JAVA_HOME=/usr/local/jdk1.7.0_79 export JAVA_HOME export PATH 验证

[root@localhost ~]# source .bash_profile [root@localhost ~]# mvn -v Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T08:41:47-08:00) Maven home: /usr/local/apache-maven-3.3.9 Java version: 1.7.0_79, vendor: Oracle Corporation Java home: /usr/local/jdk1.7.0_79/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "2.6.32-279.el6.x86_64", arch: "amd64", family: "unix" 三、安装protobuf 下载和解压

[root@localhost ~]# wget https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz [root@localhost ~]# tar xzvf ./protobuf-2.5.0.tar.gz 本地编译（依次执行下面命令）

[root@localhost ~]# cd protobuf-2.5.0 [root@localhost ~]# ./configure [root@localhost ~]# make [root@localhost ~]# make check [root@localhost ~]# make install 四、下载hadoop2.3.0源码和本地库编译 通过svn下载程序源码

[root@localhost ~]# svn checkout http://svn.apache.org/repos/asf/hadoop/common/tags/release-2.3.0 重新编译本地库

[root@localhost grid]# ls Desktop eclipse Pictures release-2.5.0 workspace Documents hadoop-2.7.3-src.tar.gz Public Templates Downloads Music release-2.3.0 Videos [root@localhost grid]# cd release-2.3.0/ [root@localhost release-2.3.0]# mvn package -Pdist,native -DskipTests -Dtar 编译过程中错误解决

错误一： JDK版本过高，原先的jdk版本为最新的1.8；

[INFO] ------------------------------------------------------------------------ [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 - /home/grid/release-2.5.0/hadoop-common-project/hadoop-annotations/src/main/java/org/apache/hadoop/classification/InterfaceStability.java:27: error: unexpected end tag: [ERROR] * [ERROR] ^ [ERROR] [ERROR] Command line was: /usr/local/jdk1.8.0_111/jre/../bin/javadoc @options @packages [ERROR] [ERROR] Refer to the generated Javadoc files in \'/home/grid/release-2.5.0/hadoop-common-project/hadoop-annotations/target\' dir. [ERROR] -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. [ERROR] Re-run Maven using the -X switch to enable full debug logging. [ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException [ERROR] [ERROR] After correcting the problems, you can resume the build with the command [ERROR] mvn -rf :hadoop-annotations

解决办法：下载1.7版本的jdk

注意修改原先配置maven时的jdk的路径

错误二： 由于网络原因，导致apache-tomcat-6.0.36.tar.gz没有构建到工程中；
