             Summary: Jenkins not starting for ci.bigtop.apache.org after reboot
                 Key: BIGTOP-4039
                 URL: https://issues.apache.org/jira/browse/BIGTOP-4039
             Project: Bigtop
          Issue Type: Task
            Reporter: Luca Toscano


After a yum upgrade + reboot of the Jenkins master node (no upgrade of its version), Jenkins fails to start due to:

2023-11-05 08:13:03.977+0000 [id=25]	SEVERE	hudson.util.BootFailure#publish: Failed to initialize Jenkins
com.thoughtworks.xstream.mapper.CannotResolveClassException: hudson.security.GlobalMatrixAuthorizationStrategy

You can see the full stacktrace via docker logs. I tried the following:
* start different versions of Jenkins (so different containers, killing the old ones etc..)
* copy matrix-auth plugin manually in the plugin dir (but it doesn't seem to work since the plugin is under /var/jenkins_home/war/WEB-INF/detached-plugins/matrix-auth.hpi)
* Checked all permissions.
* Checked packages upgraded (check /var/log/yum.log as ec2-user) but didn't find anything that could justify this.

One interesting log entry:
2023-11-05 08:09:55.541+0000 [id=33]	INFO	jenkins.InitReactorRunner$1#onAttained: Started initialization
2023-11-05 08:09:55.557+0000 [id=32]	INFO	hudson.PluginManager#loadDetachedPlugins: Upgraded Jenkins from version 2.264 to version 2.428. Loaded detached plugins (and dependencies): []

I am wondering if for some reason Jenkins can't find the detached plugins under /var/jenkins_home/war/WEB-INF/detached-plugins ?
