---------------------------------
Summary: log layer exception during shutdown that caused an
unclean shutdown
Key: KAFKA-13315
URL: https://issues.apache.org/jira/browse/KAFKA-13315
Project: Kafka
Issue Type: Bug
Reporter: Cong Ding
We have seen an exception caused by shutting down scheduler before shutting
down LogManager.
When LogManager was closing partitons one by one, scheduler called to delete
old segments due to retention. However, the old segments could have been closed
by the LogManager, which subsequently marked logdir as offline and didn't write
the clean shutdown marker. Ultimately the broker would take hours to restart.
