             Summary: Ticket Renewal Thread exits prematurely due to inverted comparison
                 Key: KAFKA-3198
                 URL: https://issues.apache.org/jira/browse/KAFKA-3198
             Project: Kafka
          Issue Type: Bug
          Components: security
    Affects Versions: 0.9.0.0
            Reporter: Adam Kunicki
            Assignee: Adam Kunicki
            Priority: Critical


Line 152 of Login.java:
{code}
if (isUsingTicketCache && tgt.getRenewTill() != null && tgt.getRenewTill().getTime() >= expiry) {
{code}

This line is used to determine whether to exit the thread and issue an error to the user.

The >= should be < since we are actually able to renew if the renewTill time is later than the current ticket expiration.
