> Add logging to distinguish between internally and externally initiated
> shutdown of Kafka
> ----------------------------------------------------------------------------------------
>
> Key: KAFKA-5679
> URL: https://issues.apache.org/jira/browse/KAFKA-5679
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.11.0.0
> Reporter: Apurva Mehta
> Assignee: Rajini Sivaram
> Fix For: 1.0.0
>
>
> Currently, if there is an internal error that triggers a shutdown of the
> Kafka server, the {{Exit}} class is used, which begins the shutdown
> procedure. The other way a shutdown is triggered is by {{SIGTERM}} or some
> other signal.
> We would like to distinguish between shutdown due to internal errors and
> external signals. This helps when debugging. Particularly, a natural question
> when a broker shuts down unexpectedly is: "did the deployment system send
> the signal or is there some un logged fatal error in the broker"?
> Today, we rely on callers of {{Exit}} to log the error before making the
> call. However, this won't always have 100% coverage. It would be good to add
> a log message in {{Exit}} to record that an exit method was invoked
> explicitly.
> We could also add a signal handler to log when {{SIGTERM}}, {{SIGKILL}} etc.
> are received.
> This would make operating Kafka a bit easier.
