New features


Resolved issues

  • FILE_PING.interval was set lower for testing purposes but this seems to contribute to chattiness.

  • CloudBees Internal Ticket: RM-1523

    [RM-1523] Circumvent UDP problems reported on CentOS by using a FILE_PING variant to discover cluster members. Unless overridden in the usual way with $JENKINS_HOME/jgroups.xml, $JENKINS_HOME/jgroups/ is now used for discovery and $JENKINS_HOME/cluster-identity.txt is no longer used since the file path determines the identity. (Also fixes [RM-1500] +warnings about packet sizes.)

  • CloudBees Internal Ticket: RM-1522

    [RM-1522] discard_incompatible_packets="false" so that it is just a warning if a user mixes different versions of jGroups between jenkins.war `and `jenkins-ha-monitor.jar.

HASingleton.demote is not called idempotently, so we need to emulate the behavior of Main in the proxy WAR.

Known issues

Java 5 is not supported by this version of high availability. Use JENKINS_HA=false to disable.
