JN need not validate finalized log segments in newEpoch

    • Type: Bug
    • Status: Open
    • Priority: Minor
    • Resolution: Unresolved

      Description

      In scanStorageForLatestEdits, the JN will call validateLog on the last log segment, regardless of whether it is finalized. If it's finalized, then this is a needless pass over the logs which can adversely affect failover time for a graceful failover.
