以下PIG代码无效:
grunt> Register /usr/lib/pig/lib/piggybank.jar ;
grunt> define Stitch org.apache.pig.piggybank.evaluation.Stitch();
grunt> data = load 'a' using PigStorage('|') ;
grunt> B = Stitch(data,data);
错误:-
2015-01-06 12:03:57,730 [main] ERROR org.apache.pig.tools.grunt.Grunt -
ERROR 1200: <line 12> Cannot expand macro 'Stitch'.
Reason: Macro must be defined before expansion.

有人可以解释这里出了什么问题.
