------------------------------
Status: Patch Available (was: Open)
> Deadlock in Background service shutdown
> ---------------------------------------
>
> Key: HDDS-14020
> URL: https://issues.apache.org/jira/browse/HDDS-14020
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Swaminathan Balachandran
> Assignee: Swaminathan Balachandran
> Priority: Major
> Labels: pull-request-available
>
> Currently both background task and shutdown acquire a synchronized lock which
> can lead to a deadlock on shutdown which means the threadPool shutdown takes
> time unnecessarily. The synchronized block on task was taken to ensure there
> are no parallel tasks that run together. Introducing a semaphore with 1 would
> solve this issue.
