pig 部署在hadoop 23上
pig-0.10.0版本是支持hadoop 23的。
但是需要重新编译pig；
编译命令如下：

ant -Dhadoopversion=23

编译好之后，把原来的pig的jar包删了就行。
当然了，hadoop的几个环境变量还是要配置的：
HADOOP_HOME

引用Pig 0.10.0 supports Hadoop 0.23.X. All unit and end-to-end tests passed with hadoop-0.23. To run Pig with hadoop-0.23, you need to recompile Pig with hadoopversion flag set to 23:
ant -Dhadoopversion=23
You also need to set up all of the environment variables necessary to run the hadoop -23 client, plus, point HADOOP_HOME to HADOOP_COMMON_HOME, and make sure $HADOOP_HOME/bin/hadoop exists.
