Patrick Hunt updated HADOOP-8149: --------------------------------- Attachment: HADOOP-8149.patch Updated patch with common only in this patch. I re-verified by running from tarball with DEBUG turned on and the maxfilesize set to just 10k. > cap space usage of default log4j rolling policy > ------------------------------------------------ > > Key: HADOOP-8149 > URL: https://issues.apache.org/jira/browse/HADOOP-8149 > Project: Hadoop Common > Issue Type: Improvement > Components: conf > Reporter: Patrick Hunt > Attachments: HADOOP-8149.patch, HADOOP-8149.patch > > > 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. -- This message is automatically generated by JIRA.
