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

             Summary: LogManager shutdown races with periodic work scheduled by the instance
                 Key: KAFKA-13070
                 URL: https://issues.apache.org/jira/browse/KAFKA-13070
             Project: Kafka
          Issue Type: Bug
            Reporter: Kowshik Prakasam


In the LogManager shutdown sequence (in LogManager.shutdown()), we don't cancel the periodic work scheduled by it prior to shutdown. As a result, the periodic work could race with the shutdown sequence causing some unwanted side effects. This is reproducible by a unit test in LogManagerTest.

 

```

// set val maxLogAgeMs = 60000 in the test

@Test
 def testRetentionPeriodicWorkAfterShutdown(): Unit = {
    val log = logManager.getOrCreateLog(new TopicPartition(name, 0), topicId = None)
     val logFile = new File(logDir, name + "-0")
     assertTrue(logFile.exists)

    log.appendAsLeader(TestUtils.singletonRecords("test1".getBytes()), leaderEpoch = 0)
     log.updateHighWatermark(log.logEndOffset)

    logManager.shutdown()

    assertTrue(Files.exists(new File(logDir, LogLoader.CleanShutdownFile).toPath))

    time.sleep(maxLogAgeMs + logManager.InitialTaskDelayMs +           logManager.retentionCheckMs + 1)

    logManager = null
 }

```
