本文记录Hadoop集群环境安装Pig。
环境：OS：Centos 6.5 x64 & Soft：Hadoop 1.2.1 & Pig 0.12
1、简介
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
