> I've seen several critical production issues because logs are not
> automatically removed after some time and accumulate. Changes to Hadoop's
> default log4j file appender would help with this.
> I recommend we move to an appender which:
> 1) caps the max file size (configurable)
> 2) caps the max number of files to keep (configurable)
> 3) uses rolling file appender rather than DRFA, see the warning here:
> http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/DailyRollingFileAppender.html
> Specifically: "DailyRollingFileAppender has been observed to exhibit
> synchronization issues and data loss."
> We'd lose (based on the default log4j configuration) the daily rolling
> aspect, however increase reliability.
