Summary: 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
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.
