第一步:下载安装包:http://mirrors.cnnic.cn/apache/pig/ (我的hadoop版本是1.2.1,我先下的pig-0.15总是提示不支持,于是我直接删了,重新下载的pig-0.13)
第二步:将下载的安装包解压:tar -xvf pig-0.13.0.tar.gz
第三步:配置环境:
1 export JAVA_HOME=/usr/lib/jvm/java-6-openjdk-i386 2 export JRE_HOME=$JAVA_HOME/jre 3 export CLASSPATH=$JAVA_HOME/bin:$JRE_HOME/bin:$CLASSPATH 4 export HADOOP_HOME=/home/xunying/hadoop-1.2.1 5 export PIG_INSTALL=/home/xunying/soft/pig-0.13.0 6 export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$HADOOP_HOME/bin:$PIG_INSTALL/bin:$PATH第四步
第四步:测试:pig

这样就成功了,记得比较简陋,只是给自己来个学习笔记,希望有帮助
