[jira] [Created] (KAFKA-2678) partition level lag metrics can be negative

Jun Rao created KAFKA-2678:
------------------------------

             Summary: partition level lag metrics can be negative
                 Key: KAFKA-2678
                 URL: https://issues.apache.org/jira/browse/KAFKA-2678
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 0.8.2.1
            Reporter: Jun Rao


Currently, the per partition level lag metric can be negative since the last committed offset can be smaller than the follower's offset. This is a bit confusing to end users. We probably should lower bound it by 0.
