----------------------------------------
Summary: ExecutorServiceParallelExecutor should have a unified
shutdown collection
Key: BEAM-4039
URL: https://issues.apache.org/jira/browse/BEAM-4039
Project: Beam
Issue Type: Improvement
Components: runner-direct
Reporter: Romain Manni-Bucau
Assignee: Thomas Groh
Goal of this ticket is to ensure the executor doesn't have to know each single
instances of what it destroys at shutdown time.
Proposal is to have a list of closeable (or autocloseable) which and a
registerCloseable which would decouple it.
Side note: it is still key to ensure the list is 1. sorted and 2. any error
doesn't prevent to call next element
