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

             Summary: StoreChangeLogReader needs to restore partitions that were added post
initialization
                 Key: KAFKA-5787
                 URL: https://issues.apache.org/jira/browse/KAFKA-5787
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 0.11.0.1, 1.0.0
            Reporter: Damian Guy
            Assignee: Damian Guy
            Priority: Blocker


Investigation of {{KStreamRepartitionJoinTest}} failures uncovered this bug. If a task fails
during initialization due to a {{LockException}}, its changelog partitions are not immediately
added to the {{StoreChangelogReader}} as the thread doesn't hold the lock. However {{StoreChangelogReader#restore}}
will be called and it sets the initialized flag. On a subsequent successfull call to initialize
the new tasks the partitions are added to the {{StoreChangelogReader}}, however as it is already
initialized these new partitions will never be restored. So the task will remain in a non-running
state forever
