使用PIG删除空格

Question

我用逗号（，）分隔（csv）数据集。每个分隔符后面有一个空格，我想在Pig脚本中删除。例如排的样子：

"Sachin", "India", "batsaman", "99", "kolkata", " ", "xyz" 

逗号后移除空格之后，它应该是这样的：

"Sachin","India","batsaman","99","kolkata"," ","xyz" 

Answer 1

加载到一个单一的领域，并使用REPLACE。

A = LOAD 'data.txt' USING TextLoader(); 
B = FOREACH A GENERATE REPLACE($0,' ','');
