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

             Summary: broker shutdown hangs when `log.segment.delete.delay.ms` 
is zero 
                 Key: KAFKA-16588
                 URL: https://issues.apache.org/jira/browse/KAFKA-16588
             Project: Kafka
          Issue Type: Bug
            Reporter: Chia-Ping Tsai
            Assignee: Chia-Ping Tsai


see 
https://github.com/apache/kafka/blob/f22ad6645bfec0b38e820e0090261c9f6b421a74/core/src/main/scala/kafka/log/LogManager.scala#L1154

We call `take` even though the `logsToBeDeleted` is empty, and 
`KafkaScheduler#shutdown` call `shutdown` rather than `shudownNow` 
([https://github.com/apache/kafka/blob/trunk/server-common/src/main/java/org/apache/kafka/server/util/KafkaScheduler.java#L134)]

Hence, the thread won't be completed forever, and it blocks the shutdown of 
broker.

We should replace the `take` by `poll` since we have checked the element before.
