Pig Schema 错误意外字符“：”

Question

我正在尝试创建一个以 2B:chararray 作为一列名称的猪模式。它给我一条错误消息

2B:chararray Unexpected character ':'

如果将其删除，则会创建架构。这里有什么问题？

架构是

load 'Batting.csv' using org.apache.pig.piggybank.storage.CSVExcelStorage(',','YES_MULTILINE','NOCHANGE','SKIP_INPUT_HEADER') as (yearID:int, sting:chararray, teamID:chararray, lgID:chararray, G:chararray, G_batting:chararray, AB:chararray, R:chararray, H:chararray, 2B:chararray);

Answer 1
