（1）安装–xzfPig-0.9.2-tar.gz，，并重命名为pig;
（2）在/etc/profile文件里面添加下面内容：
vim/etc/profile
#setpigpath
exportPIG_HOME=/usr/pig
exportPATH=${PIG_HOME}/bin:${PATH}
然后source/etc/profile使其生效；
（3）在pig.properties，在其中添加指向logs的路径：pig.logfile=/usr/pig/logs
（4）然后测试
[hadoop@Masterpc~]$pig

（5）接下来就进行实战了：问题说明：由于电信公司一般把通话记录
（6）假设关系数据库有一个

假设：查询任务是查询开始时间是XXX，被叫号码是由于cdr.txt存放后如下所示：

出现上述错误：经过
经过一番的调试后，终于找出了问题的所在：为之前搭建，现在只需要把hadoop/lib执行下面命名：
[hadoop@Masterpclib]$rm-rantlr-runtime-3.0.1.jar
删除后，重新执行pig程序：
