             Summary: Failures in the StateUpdater thread may lead to inability 
to shut down a stream thread
                 Key: KAFKA-19831
                 URL: https://issues.apache.org/jira/browse/KAFKA-19831
             Project: Kafka
          Issue Type: Bug
          Components: streams
            Reporter: Nikita Shupletsov
         Attachments: StateUpdaterFailureIntegrationTest.patch

If during rebalance a failure occurs in the StateUpdater thread, and this 
failure leads to the thread shutdown, the Stream thread may get into an 
infinite wait state during it's shutdown.

See the attached test that reproduces the issue.
