将 java 文件导入 pig

Question

rawGSODData = LOAD '/usr/local/Cellar/pig/0.12.0/gsod_2016/999999-93816-2016.op.gz' USING org.apache.pig.piggybank.storage.FixedWidthLoader('

'SKIP_HEADER');

当我尝试运行这段代码时，我会收到一条错误消息

 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FixedWidthLoader.java中有文件

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

请帮我解决这个错误

Answer 1

REGISTER '/usr/local/piggybank.jar';
