当我尝试运行此代码时，我会收到一条错误

 ERROR 1070: Could not resolve org.apache.pig.piggybank.storage.FixedWidthLoader using imports: [, java.lang., org.apache.pig.builtin., org.apache.pig.impl.builtin.]

我在目录

中有文件FixedWidthLoader.java文件

/usr/local/Cellar/pig/0.12.0/build/classes/org/apache/pig/piggybank/storage

请帮我解决此错误

Answer 1

piggybank.jar在哪里？确保你已经在Pig脚本中注册了piggybank.jar。如果没有，请将它添加到pig脚本的顶部。确保piggybank.jar的路径是正确的.Below语句注册jar文件，即位于/ usr / local /中的piggybank

CHARACTER SET utf8

将java文件导入pig
