  1. As the extras features are not shipped with the default log4j implementation hence the users will need to download the "Apache Extras™ for Apache log4j" (Like: apache-log4j-extras) :

    Example: For example download the jar "apache-log4j-extras-1.2.17.jar" and place it inside the location:


    2. Add the property -Dhadoop.root.logger=INFO,ZIPRFA to export AMBARI_JVM_ARGS parameter in /var/lib/ambari-server/

    export AMBARI_JVM_ARGS=$AMBARI_JVM_ARGS' -Xms512m -Xmx2048m -Dhadoop.root.logger=INFO,ZIPRFA'

    3. Uncomment/Add the server classpath in /var/lib/ambari-server/

    export SERVER_CLASSPATH=/etc/hadoop/conf/secure

    4. Added the following property to log4j:


    Comment out the following values:

    # Direct log messages to a log file
    #log4j.appender.file.layout.ConversionPattern=%d{DATE} %5p [%t] %c{1}:%L - %m%n

    Add the following values:

    #### New Appender to Zip the Log Files Based on Daily Rotation
    log4j.appender.ZIPRFA.layout.ConversionPattern=%d{ISO8601} %p %c: %m%

    5. Run ps -ef | grep ambari and check for -Dhadoop.root.logger=INFO,EWMA,RFA

    6. Now restart ambari server and check for -Dhadoop.root.logger again, it should have been changed to -Dhadoop.root.logger=INFO,ZIPRFA

    Now when the date changes, ambari server logs would be rolled over.
