What happens if controlled shutdown can't complete within controlled.shutdown.max.retries attempts?

[James Cheng <jc...@tivo.com>]

The broker has the following parameters related to controlled shutdown:

controlled.shutdown.enable      Enable controlled shutdown of the server        boolean true            medium
controlled.shutdown.max.retries Controlled shutdown can fail for multiple reasons. This determines the number of retries when such failure happens      int     3               medium
controlled.shutdown.retry.backoff.ms    Before each retry, the system needs time to recover from the state that caused the previous failure (Controller fail over, replica lag etc). This config determines the amount of time to wait before retrying. long    5000            medium


If the broker attempts controlled shutdown and then fails, and this happens controlled.shutdown.max.retries number of times, what happens? Does it go back into active service and continue participating in the cluster, as if controlled shutdown never happened? Or does it do an uncontrolled shutdown?

Thanks,
-James
