1、简介

项目主页：https://pig.apache.org/

下载二进制安装包pig-0.12.0.tar.gz，上传到服务器。

2、安装

用集群环境普通用户安装，解压安装包。

[huser@master hadoop]$ tar -xvf pig-0.12.0.tar.gz 

3、配置环境变量

[huser@master ~]$ vi /etc/profile

export JAVA_HOME=/usr/java/jdk1.7.0_51
export CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar 
export JRE_HOME=$JAVA_HOME/jre 
export HADOOP_HOME=/home/huser/hadoop/hadoop-1.2.1
export HADOOP_CONF_DIR=/home/huser/hadoop/hadoop-1.2.1/conf
export HADOOP_CLASSPATH=/home/huser/hadoop/hadoop-1.2.1/bin
export MAHOUT_HOME=/home/huser/hadoop/mahout-distribution-0.9
export MAHOUT_HOME_DIR=/home/huser/hadoop/mahout-distribution-0.9/conf
export PIG_HOME=/home/huser/hadoop/pig-0.12.0
export PIG_CLASSPATH=/home/huser/hadoop/pig-0.12.0/conf
export PATH=$PATH:$JAVA_HOME/bin:$PIG_HOME/bin:$PIG_HOME/conf:$MAHOUT_HOME/bin:$MAHOUT_HOME/conf

[root@master huser]# source /etc/profile

4、测试

[huser@master hadoop]$ pig
