How to rotate zookeeper daemon/console log

On my zookeeper log4j configuration, I have logger for console and rolling file.

I ran my zookeeper using systemctl.

In zookeeper/bin/zkServer.sh, there's this line _ZOO_DAEMON_OUT="$ZOO_LOG_DIR/zookeeper.out" which I assume is where the console logger for zookeeper.

One day the zookeeper.out got too big, and to clean it up, I need to stop zookeeper, delete zookeeper.out, and start zookeeper.

Question: Is there a way to rotate the zookeeper.out?

Solution

  • You need to remove the CONSOLE log appender from your log4j properties. Please check out this post on Cloudera.

    Just switch to ROLLINGFILE instead.

    log4j.rootLogger=INFO, ROLLINGFILE
log4j.appender.ROLLINGFILE.File=${zookeeper.log.dir}/zookeeper.log 
log4j.appender.ROLLINGFILE.MaxFileSize=5MB
log4j.appender.ROLLINGFILE.MaxBackupIndex=10
