Hadoop源码编译
准备工作
(1)CentOS联网
配置CentOS能连接外网。Linux虚拟机ping是畅通的注意:采用root角色编译,减少文件夹权限出现问题
(2)jar包准备(hadoop源码、JDK8、maven、ant 、protobuf)
(1)hadoop-2.7.2-src.tar.gz(2)jdk-8u144-linux-x64.tar.gz(3)apache-ant-1.9.9-bin.tar.gz(build工具,打包用的)(4)apache-maven-3.0.5-bin.tar.gz(5)protobuf-2.5.0.tar.gz(序列化的框架)
编译工具安装
(1)安装JDK
[root@hadoop101 software] # tar -zxf jdk-8u144-linux-x64.tar.gz -C /opt/module/[root@hadoop101 software]# vi /etc/profile\#JAVA_HOME:export JAVA_HOME=/opt/module/jdk1.8.0_144export PATH=$PATH:$JAVA_HOME/bin[root@hadoop101 software]#source /etc/profile验证命令:java -version
(2)Maven解压、配置 MAVEN_HOME和PATH
[root@hadoop101 software]# tar -zxvf apache-maven-3.0.5-bin.tar.gz -C /opt/module/[root@hadoop101 apache-maven-3.0.5]# vi conf/settings.xml<mirrors> <!-- mirror | Specifies a repository mirror site to use instead of a given repository. The repository that | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used | for inheritance and direct lookup purposes, and must be unique across the set of mirrors. |<mirror> <id>mirrorId</id> <mirrorOf>repositoryId</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://my.repository.com/repo/path</url> </mirror> --> <mirror> <id>nexus-aliyun</id> <mirrorOf>central</mirrorOf> <name>Nexus aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url> </mirror></mirrors>[root@hadoop101 apache-maven-3.0.5]# vi /etc/profile\#MAVEN_HOMEexport MAVEN_HOME=/opt/module/apache-maven-3.0.5export PATH=$PATH:$MAVEN_HOME/bin[root@hadoop101 software]#source /etc/profile验证命令:mvn -version
(3)配置ANT
[root@hadoop101 software]# tar -zxvf apache-ant-1.9.9-bin.tar.gz -C /opt/module/[root@hadoop101 apache-ant-1.9.9]# vi /etc/profile\#ANT_HOMEexport ANT_HOME=/opt/module/apache-ant-1.9.9export PATH=$PATH:$ANT_HOME/bin[root@hadoop101 software]#source /etc/profile验证命令:ant -version
(4)安装 glibc-headers 和 g++
[root@hadoop101 apache-ant-1.9.9]# yum install glibc-headers[root@hadoop101 apache-ant-1.9.9]# yum install gcc-c++
(5)安装make和cmake
[root@hadoop101 apache-ant-1.9.9]# yum install make[root@hadoop101 apache-ant-1.9.9]# yum install cmake
(6)安装protobuf
[root@hadoop101 software]# tar -zxvf protobuf-2.5.0.tar.gz -C /opt/module/[root@hadoop101 opt]# cd /opt/module/protobuf-2.5.0/[root@hadoop101 protobuf-2.5.0]#./configure [root@hadoop101 protobuf-2.5.0]# make [root@hadoop101 protobuf-2.5.0]# make check [root@hadoop101 protobuf-2.5.0]# make install [root@hadoop101 protobuf-2.5.0]# ldconfig [root@hadoop101 hadoop-dist]# vi /etc/profile\#LD_LIBRARY_PATHexport LD_LIBRARY_PATH=/opt/module/protobuf-2.5.0export PATH=$PATH:$LD_LIBRARY_PATH [root@hadoop101 software]#source /etc/profile验证命令:protoc --version
(7)安装openssl库
[root@hadoop101 software]#yum install openssl-devel
(8)安装 ncurses-devel库
[root@hadoop101 software]#yum install ncurses-devel到此,编译工具安装基本完成
编译源码
(1)解压源码到/opt/目录
[root@hadoop101 software]# tar -zxvf hadoop-2.7.2-src.tar.gz -C /opt/
(2)进入到hadoop源码主目录
[root@hadoop101 hadoop-2.7.2-src]# pwd/opt/hadoop-2.7.2-src
(3)通过maven执行编译命令
[root@hadoop101 hadoop-2.7.2-src]#mvn package -Pdist,native -DskipTests -Dtar等待时间30分钟左右,最终成功是全部SUCCESS
# 成功的64位hadoop包在/opt/hadoop-2.7.2-src/hadoop-dist/target下[root@hadoop101 target]# pwd/opt/hadoop-2.7.2-src/hadoop-dist/target
(4)编译源码过程中常见的问题及解决方案
(1)MAVEN install时候JVM内存溢出处理方式:在环境配置文件和maven的执行文件均可调整MAVEN_OPT的heap大小。(详情查阅MAVEN 编译 JVM调优问题,如:http://outofmemory.cn/code-snippet/12652/maven-outofmemoryerror-method)(2)编译期间maven报错。可能网络阻塞问题导致依赖库下载不完整导致,多次执行命令(一次通过比较难):[root@hadoop101 hadoop-2.7.2-src]#mvn package -Pdist,nativeN -DskipTests -Dtar(3)报ant、protobuf等错误,插件下载未完整或者插件版本问题,最开始链接有较多特殊情况,同时推荐
