Erick Erickson commented on SOLR-7887: -------------------------------------- Patch with my reviewboard comments except the two that refer to log4j1.2, I'm not sure whether those are in there for back compat or not. Fixed up the CHANGES.txt issues I think too. See: https://reviews.apache.org/r/65888/ > Upgrade Solr to use log4j2 -- log4j 1 now officially end of life > ---------------------------------------------------------------- > > Key: SOLR-7887 > URL: https://issues.apache.org/jira/browse/SOLR-7887 > Project: Solr > Issue Type: Task > Affects Versions: 5.2.1 > Reporter: Shawn Heisey > Assignee: Varun Thacker > Priority: Major > Attachments: SOLR-7887-WIP.patch, SOLR-7887-eoe-review.patch, > SOLR-7887.patch, SOLR-7887.patch, SOLR-7887.patch, SOLR-7887.patch, > SOLR-7887.patch, SOLR-7887.patch, SOLR-7887.patch, SOLR-7887.patch, > SOLR-7887.patch > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
