[jira] [Created] (KAFKA-3211) Handle WorkerTask shutdown before startup correctly

Jason Gustafson created KAFKA-3211:
--------------------------------------

             Summary: Handle WorkerTask shutdown before startup correctly
                 Key: KAFKA-3211
                 URL: https://issues.apache.org/jira/browse/KAFKA-3211
             Project: Kafka
          Issue Type: Bug
          Components: copycat
            Reporter: Jason Gustafson
            Assignee: Jason Gustafson


This is a follow-up from KAFKA-3092. The shortcut exit from awaitShutdown() in WorkerTask can lead to an inconsistent state if the task has not actually begun execution yet. Although the caller will believe the task has completed shutdown, nothing stops it from starting afterwards. This could happen if there is a long delay between the time a task is submitted to an Executor and the time it begins execution.
