             Summary: Recover segment does shallow iteration to fix index 
causing inconsistencies
                 Key: KAFKA-866
                 URL: https://issues.apache.org/jira/browse/KAFKA-866
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.8
            Reporter: Sriram Subramanian
            Assignee: Sriram Subramanian
            Priority: Blocker


When we recover a segment, we do a shallow iteration to fix the index. This 
creates entries in the index with the last logical offset in a compressed 
messageSet. However, during log append we use the starting offset in a 
compressed message set to populate the index (We changed to starting offset 
recently). This causes inconsistencies.
