Nope, But if the intent is so then there are 2 ways of doing it. 1. Just extend the input format of your choice and override isSplitable() method to return false.
2. Compress your text file using a compression format supported by hadoop (e.g gzip). This will ensure that one map task processes 1 file since compressed files are not split between processes. -----Original Message----- From: Qiong Zhang [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 01, 2008 9:54 PM To: [email protected] Subject: one input file per map Hi, Is there an existing input format/split which supports one input file (e.g. plain text) per map task? Thanks, James
