[jira] [Created] (BEAM-4039) ExecutorServiceParallelExecutor should have a unified shutdown collection

Romain Manni-Bucau created BEAM-4039:
----------------------------------------

             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
