CentOS6.7-64bit编译hadoop2.6.4

1.下载maven(apache-maven-3.3.3-bin.tar.gz)
  http://archive.apache.org/dist/maven/maven-3/3.3.3/binaries/apache-maven-3.3.3-bin.tar.gz
2.安装maven
  tar -zxvf apache-maven-3.3.3-bin.tar.gz -C /usr/local
3.添加环境变量
vim /etc/profile

  export JAVA_HOME=/usr/local/jdk1.7.0_45
  export MAVEN_HOME=/usr/local/apache-maven-3.3.3
  export PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin

4.加载环境变量
source /etc/proflie
mvn -version

5.下载protobuf

  (https://code.google.com/p/protobuf/downloads/list 或 https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz)

6.安装protobuf编译依赖,为了编译安装protoc,需要使用YUM下载几个依赖的工具
  yum install -y gcc gcc-c++ make

7.解压安装protobuf(root 用户下执行)
  tar -zxvf protobuf-2.5.0.tar.gz -C /usr/local/src
  cd /usr/local/src/protobuf-2.5.0
  ./configure --prefix=/usr/local/protobuf
  make && make install

8.将protobuf添加到环境变量
  vim /etc/profile

  export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$MAVEN_HOME/bin:/usr/local/protobuf/bin

  source /etc/profile

  protoc --version

9.安装其他编译依赖
  yum install -y cmake openssl-devel ncurses-devel zlib-devel
  yum install -y snappy snappy-devel bzip2 bzip2-devel lzo lzo-devel lzop openssl openssl-devel

10.编译hadoop(进入文件夹里面,里面有一个文件BUILDINT.txt,打开即可看见里面关于编译hadoop的一些环境要求)
  tar -zxvf hadoop-2.6.4-src.tar.gz -C /usr/local/src/
  cd /usr/local/src/hadoop-2.6.4-src


  mvn package -Pdist,native -DskipTests -Dtar

12.查看编译好的安装包
  cd /usr/local/src/hadoop-2.6.4-src/hadoop-dist/target


#出现问题
INFO util.NativeCodeLoader - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

在/etc/profile中添加
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib/native"

#查看可用的本地库
hadoop checknative -a

cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc –l
cat /proc/cpuinfo | grep "core id" | sort -u | wc -l
cat /proc/cpuinfo | grep MHz | uniq
