hadoop编译和spark编译

编译hadoop

1.下载maven（apache-maven-3.3.3-bin.tar.gz）（3.0.5以上版本）
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
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

编译spark

maven版本最好

tar -zxvf spark-1.6.1.tgz -C /usr/local/src/
cd /usr/local/src/spark-1.6.1/

#设置内存2G
export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m"

#编译前安装一些压缩解压缩工具
yum install -y snappy snappy-devel bzip2 bzip2-devel lzo lzo-devel lzop openssl openssl-devel

#仅仅是为了编译源码, 编译后可以导入idea中
mvn clean package -Phadoop-2.6 -Dhadoop.version=2.6.4 -Phive -Phive-thriftserver -Pyarn -DskipTests

#编译后并打包, 打包后可以丢到生产环境了
./make-distribution.sh --tgz -Phadoop-2.6 -Dhadoop.version=2.6.4 -Phive -Phive-thriftserver -Pyarn -DskipTests 

cd spark-1.3.1

export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m"

mvn clean package -Phadoop-2.6 -Dhadoop.version=2.6.4 -Phive -Phive-thriftserver -Pyarn -DskipTests

./make-distribution.sh --tgz -Phadoop-2.6 -Dhadoop.version=2.6.4 -Phive -Phive-thriftserver -Pyarn -DskipTests
