[jira] [Updated] (HBASE-5655) Cap space usage of default log4j rolling policy
[ https://issues.apache.org/jira/browse/HBASE-5655?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Himanshu Vashishtha updated HBASE-5655: --- Release Note: This changes the default log rolling scheme from DRFA to RFA. The former rolls over the log on a date change trigger, while the later rolls over when the log file size reaches a predefined limit. The issue with DRFA is that it doesn't have the ability to cap the space usage, so users who are not using host-level log rotation might fill up their log partitions. This results in a cluster crash. RFA puts a size limit on the log size and therefore is a safer option in such scenarios. The default file size is 256MB with 20 files (total of 5GB logs). In case one needs to revert to the original DRFA (for some legacy tools etc), one can set a env variable HBASE_ROOT_LOGGER to ROOT_LOGGER_LEVEL,DRFA. Please refer to the hbase-env.sh for more details.

At times, its good to have a cap on the maximum size of the logs in order to limit its disk usage. Here is a proposal to set a new file appemder (RFA) as the default appender. It can be configured via env so that existing tools can use the current behavior of using DRFA instead. This is in parallel with jira Hadoop-8149. -- This message is automatically generated by JIRA.
