[cat mys <di...@hotmail.com>]

Hello,I 'm currently developing a MapReduce application, and i want my Map job to takemore data than a single line as the default configuration does (eg 64kb input split size).How can i change the input split size for the Map job? Are there any configuration files that i have to edit or a class'field that needs to be changed?I tried to change the appropriate field in FileIputFormat class but nothing changed.ThanksC.
