  • 1.  Upgrade log4j1 to log4j2 in pentaho

    Posted 10 days ago
    Hi All,

    we wanted to upgrade log4j1 to log4j2.17.0 in pentaho 8.0 community version.
    what are the steps to be taken care?
    Anyone upgraded and faced any issue?

    Thanks,
    Divya.

    Hi Divya

    https://logging.apache.org/log4j/log4j-2.2/manual/migration.html  lays out the rules for migration"

    They must not access methods and classes internal to the Log4j 1.x implementation such as Appenders, LoggerRepository or Category's callAppenders method.​

    grepping through the kettle-engine repo I can see (among others)

    plugins/log4j/core/src/main/java/org/pentaho/di/core/logging/Log4jConsoleAppender.java:import org.apache.log4j.Appender;

    so I'd guess it requires significant code updates and testing.
