我正在尝试使用以下代码枚举一个包：

DEFINE Enumerate datafu.pig.bags.Enumerate('1');

  group = GROUP data1
            By (query_text);

  ranked = FOREACH group {
        ordered = ORDER data1 BY score DESC;
        ordered = Enumerate(ordered);
        generate ordered_suggestions;
    };

获取以下错误：

220255 [main] ERROR org.apache.pig.tools.grunt.Grunt  - ERROR 1070: Could not resolve datafu.pig.bags.Enumerate using imports: [, java.lang., org.apache.pig.builtin., org.apache.pig.impl.builtin.]

我没有注册jar。

REGISTER 's3:/<<s3-bucket-name>>/lib/datafu-1.2.0.jar';

这很好：

REGISTER 's3:/<<s3-bucket-name>>/lib/datafu-1.2.0.jar
 DEFINE Enumerate datafu.pig.bags.Enumerate('1');

  group = GROUP data1
            By (query_text);

  ranked = FOREACH group {
        ordered = ORDER data1 BY score DESC;
        ordered = Enumerate(ordered);
        generate ordered_suggestions;
    };
