Details

    • Improvement
    • Status: In Progress
    • Major
    • Resolution: Unresolved
    • 3.4.0, 3.3.5
    • None
    • journal-node

    • Running in Kubernetes using Java 11, with an HA configuration.

    Description

      During the JournalNode startup, it builds the list of servers in the JournalNode set, ignoring hostnames that cannot be resolved.  In environments with dynamic IP address allocations this means that the JournalNodeSyncer will never sync with hosts that aren't resolvable during startup.
