We are looking for ways to prevent Hadoop daemon logs from piling up (over time they can reach several tens of GB and become a nuisance). Unfortunately, the log4j DRFA class doesn't seem to provide an easy way to limit the number of files it creates. I would like to try switching to RFA with set MaxFileSize and MaxBackupIndex, since it looks like that's going to solve the log accumulation problem, but I can't figure out how to change the default logging class for the daemons. Can anyone give me some hints on how to do it?
Alternatively, please let me know if there's a better solution to control log accumulation. Thanks, --Leo
