Apache pig 无法从Pig脚本中的包中读取数据/

您能告诉我，如果我有{，'，）分隔字段和行李数据，如何读取。我得到下面的错误

对于上述输入，不需要regex，您可以使用现有模式本身访问所有值

input.txt

转储D的输出：

bfile= LOAD 'input.txt' using PigStorage('|') as (name:chararray,team:chararray,pos:bag{t:(p:chararray)},bat:map[]);

--Print the name and team
B = FOREACH bfile GENERATE name,team;

在包中，如果需要多个字段，那么像这样声明和访问

pos:bag{t:(p:chararray,q:charrarray)}
FOREACH bfile GENERATE name,pos.(p,q);

我没有看到名字和球队（即豪尔赫·波萨达·扬基）之间的分隔符“|”，它是一个空格，这是应该的吗？在给定的输入中，第三行是“，”作为位置和击球之间的分隔符。这是应该的吗？嘿，我已经更新了数据。很抱歉。bfile=LOAD'/home/cloudera/basketball.txt”使用PigStorage（“|”）作为（名称：查拉雷，团队：查拉雷，团队：查拉雷，pos：袋：{t：（p：查拉雷）}，bat：地图[））；乔治·波萨达（美国洋基队）{{（捕手，（指定的打击者）}124；[队队：队：队：队：查拉雷，队：队：队：队：队：队：队，队：队：队：队，队：队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队，队：队，队，队：队：队：队：队：队：队：队：队：队：队：队：队：队：队：队：队：队：队：队：队：棒球手，（内野手，（左外野手）}|[游戏258，投球命中率3]我能够成功加载和访问上述数据。错误似乎出现在脚本的第27行。错误1200:。您可以粘贴pig脚本的第27行吗？我只使用了一个linie来读取文件。我不知道为什么它指向第27行。您能用一些示例帮助我理解正则表达式操作或用法吗。我在论坛上看到你写了很多关于这方面的文章。请用一些示例来解释我。谢谢Siva。我知道这个正则表达式是不需要的。但是我只想在我的POC中使用一些数据。但是我真的不理解这个概念。你能在这里详细说明一下吗。请。非常感谢Siva。它工作得很好…但是请解释一下关于正则表达式。Cool.请将此问题标记为已回答。确定您想从regex获得什么？您能告诉我您到底需要什么吗？siva在哪里做这件事..请让我知道…关于regex摘录，您有任何文档或链接来了解基本知识..我对此一无所知..单击回答部分左侧的勾号按钮。对于regex，我通常使用nd来模拟正则表达式
