[jira] [Commented] (SOLR-7887) Upgrade Solr to use log4j2 -- log4j 1 now officially end of life

    [ https://issues.apache.org/jira/browse/SOLR-7887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15069914#comment-15069914 ] 

Shawn Heisey commented on SOLR-7887:
------------------------------------

[~thelabdude], I think it's time to work on this.  Your implementation of LogWatcher for log4j2 would be a prerequisite.  Should that be its own issue, or part of this one?

> The logging services project has officially announced the EOL of log4j 1:
> https://blogs.apache.org/foundation/entry/apache_logging_services_project_announces
> In the official binary jetty deployment, we use use log4j 1.2 as our final logging destination, so the admin UI has a log watcher that actually uses log4j and java.util.logging classes.  That will need to be extended to add log4j2.  I think that might be the largest pain point to this upgrade.
> There is some crossover between log4j2 and slf4j.  Figuring out exactly which jars need to be in the lib/ext directory will take some research.
