---------------------------------
Chris, I think this might help with what you're asking:
http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/DailyRollingFileAppender.html
We use it in our hive log4j configs and have something like this.
{code}
hive.root.logger=WARN,DRFA
hive.log.dir=/my/log/path/${user.name}
hive.log.file=hive.log
# Define the root logger to the system property "hadoop.root.logger".
log4j.rootLogger=${hive.root.logger}, EventCounter
# Logging Threshold
log4j.threshhold=WARN
#
# Daily Rolling File Appender
#
log4j.appender.DRFA=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DRFA.File=${hive.log.dir}/${hive.log.file}
# Rollver at midnight
log4j.appender.DRFA.DatePattern=.yyyy-MM-dd
# 30-day backup
#log4j.appender.DRFA.MaxBackupIndex=30
log4j.appender.DRFA.layout=org.apache.log4j.PatternLayout
# Pattern format: Date LogLevel LoggerName LogMessage
#log4j.appender.DRFA.layout.ConversionPattern=%d{ISO8601} %p %c: %m%n
# Debugging Pattern format
log4j.appender.DRFA.layout.ConversionPattern=%d{ISO8601} %-5p %c{2} (%F:%M(%L))
- %m%n

> Roll gc logs in run-class.sh
> ----------------------------
>
> Key: SAMZA-20
> URL: https://issues.apache.org/jira/browse/SAMZA-20
> Project: Samza
> Issue Type: Bug
> Components: container
> Affects Versions: 0.6.0
> Reporter: Chris Riccomini
> Assignee: Rekha Joshi
> Labels: newbie
>
> The run-class.sh script defaults to setting up a gc.log file, if SAMZA_OPTS
> is undefined.
> Newer versions of Java 6, and Java 7 allow you to roll gc log files with
> -XX:+UseGCLogFileRotation. See
> http://stackoverflow.com/questions/3822097/rolling-garbage-collector-logs-in-java
> for details.
> Should also validate that the change doesn't break with older Java 6 versions.
> Also, [~sureshms] was saying that there's an alternate way to do this. Suresh
> - care to chime in?
