-----------------------------------
Summary: [core] More graceful CallableQueueService#destroy()
Key: OOZIE-3357
URL: https://issues.apache.org/jira/browse/OOZIE-3357
Project: Oozie
Issue Type: Improvement
Components: core
Affects Versions: 5.1.0
Reporter: Andras Piros
Fix For: 5.2.0
In OOZIE-3160 {{CallableQueueService}} has been refactored. It seems like not
all the {{XCallable}} elements are processed when one of the
{{ExecutorService}} instances are shut down.
Following issues to investigate:
# {{ThreadPoolExecutor#awaitTermination()}} gets stuck even if no
{{XCallable}} elements are present anymore
# await termination only conditionally, that is, when there are still some
{{XCallable}} elements in one of the {{ThreadPoolExecutor}} instances
