[jira] [Closed] (FLINK-27724) The SubtaskCheckpointCoordinatorImpl#close() isn't called in anywhere

["Piotr Nowojski (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLINK-27724?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Piotr Nowojski closed FLINK-27724.
----------------------------------
    Resolution: Not A Problem

As [~fanrui] pointed out in an offline discussion, {{SubtaskCheckpointCoordinatorImpl}} is actually closed via call stack:
# org.apache.flink.streaming.runtime.tasks.StreamTask#cleanUp
# resourceCloser.close();
# and combination of {{resourceCloser.registerCloseable(cancelables);}} + registering {{SubtaskCheckpointCoordinatorImpl}} in {{cancelables}}.

Thanks for spotting this.
