We use Hadoop 0.20.2 version.The log4j.properties file has a
property *hadoop.tasklog.logsRetainHours *(mentioned as 24 hours by default)
* *which we have set to 12.Despite this property being set we still have
old userlogs in the system.Any idea why the attempt directories (that have
the syserr/sysout files) have not been cleaned up? Are we missing any other
Any help on this topic would be great.
