如果您想使用 mapreduce 处理文本文件或日志文件，默认情况下映射器输入值 ll ba 排成换行符，但我想处理日志文件
A (18:18:43,703 [ERROR] AccStmtGeneratorImpl - Statement not generated for::304005)
B (11:40:04,202 [ERROR] JobStoreTX - Failed to close Connection
java.sql.SQLException: Already closed.

)
在这里，我的映射器应该从 11:40:04,202 取值到新的时间戳，这意味着 A 将是一个值，整个 B 将是另一个值，所以我该怎么做..？提前谢谢请帮忙...
