----------------------------------

             Summary: OffsetIndex thread safety
                 Key: KAFKA-3510
                 URL: https://issues.apache.org/jira/browse/KAFKA-3510
             Project: Kafka
          Issue Type: Bug
            Reporter: Ismael Juma
            Assignee: Ismael Juma
             Fix For: 0.10.0.0


We expose non-volatile variables without a lock and outside the class. We also 
use an `AtomicInteger` unnecessarily since it's always modified within a lock.
