> Cancel pending health check on NodeStateManager close
> -----------------------------------------------------

> Key: HDDS-16926
> URL: https://issues.apache.org/jira/browse/HDDS-16926
> Project: Apache Ozone
> Issue Type: Improvement
> Components: SCM
> Reporter: Siyao Meng
> Assignee: Siyao Meng
> Priority: Major
> Labels: pull-request-available
>
> {{NodeStateManager}} schedules its health check as a one-shot task
> {{ozone.scm.heartbeat.thread.interval}} (3s by default) in the future, and
> reschedules it after each run. {{close()}} calls
> {{executorService.shutdown()}}, which still lets already scheduled delayed
> tasks run, and then {{awaitTermination}}. As a result {{close()}} blocks
> until the pending health check fires, up to 3s.
> This delays every SCM stop, and every test that closes a real
> {{SCMNodeManager}} pays the wait once per test. For example
> {{TestDeletedBlockLog}} takes about 100s in CI, more than 80s of which is
> this wait.
> Proposed fix: cancel the pending health check in {{close()}} before shutting
> down the executor.
