Centos7编译Hadoop-2.7.5遇到的坑

一、下载源码

　　地址：http://mirrors.hust.edu.cn/apache/hadoop/common/hadoop-2.7.5/hadoop-2.7.5-src.tar.gz二、
　　解压缩 tar zxvf hadoop*.src.tar.gz -C 指定解压目录

三、用IDEA打开，因为IDEA配置了MAVEN，自动识别为maven项目

四、编译

　　clean install package -Pdist,native -DskipTests -Dtar

五、遇到的坑

　　首先要安装ant，yum install ant

　　① findbugs

       下载连接，可能比较慢：https://jaist.dl.sourceforge.net/project/findbugs/findbugs/3.0.1/findbugs-3.0.1.tar.gz

　　② protobuf ：

　　关键字:protobuf

　　编译安装，配置环境变量便可

[ERROR] Failed to execute goal org.apache.hadoop:hadoop-maven-plugins:2.7.1:protoc (compile-protoc) on project hadoop-common: org.apache.maven.plugin.MojoExecutionException: ‘protoc –version’ did not return a version -> [Help 1]

　　③cmake：若是没有安装须要先安装cmake

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (make) on project hadoop-common: An Ant BuildException has occured: 
exec returned: 1 [ERROR] around Ant part …<exec dir=”/home/work/workplace/hadoop/hadoop-2.7.5/hadoop-common-project/hadoop-common/target/native” executable=”cmake” 
failonerror=”true”>… @ 4:152 in /home/linuxidc/workplace/hadoop/hadoop-2.6.0-src/hadoop-common-project/hadoop-common/target/antrun/build-main.xml

　　关键词：cmake，查看cmake是否安装，cmake -version，已存在，经百度，须要安装另外两个库

　　centos下命令是：yum install zlib-devel，openssl-devel

　　若是不能联网就去百度找包下载下来放上去吧
