如果你想用mapreduce处理文本文件或日志文件，默认情况下mapper输入值ll b一行到新行字符但是我想处理一个日志文件
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.
at org.apache.commons.dbcp.PoolableConnection.close(PoolableConnection.java:114)
at `enter code here`org.apache.commons.dbcp.PoolingDataSource$PoolGuardConnectionWrapper.close(PoolingDataSource.java:191)

这里我的mapper应该从11：40：04,202取值到新的时间戳意味着A＆＃39; ll是一个值而整个B ll b另一个值 那怎么能这样做..？ 提前致谢 请帮忙......
